Primary acinic cell carcinoma of the breast: A case report and review of literature

BACKGROUND In the current World Health Organization classification,acinic cell carcinoma(AcCC)of the breast is considered a rare histological subtype of triple-negative breast cancer.Because of the few reports in the literature,data concerning clinical outcomes are limited.Here,we report a case of AcCC of the breast in a 48-year-old woman.A 48-year-old woman with a mass in her right breast came to our hospital for further diagnosis.Mammography and an ultrasound(US)scan showed a mass in the upper inner side of the right breast.She then underwent surgery to resect the mass in her right breast.Postoperative pathological examination revealed that the tumor had abundant acinar-like structures formed by tumor cells with prominent eosinophilic granules in the cytoplasm,consistent with acinar cell carcinoma.The results of immunohistochemical analysis supported the diagnosis of breast acinar cell carcinoma.Two months later,she underwent breast-conserving surgery and sentinel lymph node biopsy.The pTNM stage was T2N0M0.After surgery,the patient received 30 radiotherapy sessions.The patient was followed up for a period of one year,and no recurrence was found.AcCC of the breast is a rare type of malignant tumor.Because it is usually asym-ptomatic and can be detected by imaging studies,routine breast US or mamm-ograms are important.However,there are no characteristic diagnostic imaging findings or clinical manifestations,so immunohistochemical examination is critical for an accurate diagnosis of AcCC of the breast.

Polo-like kinase 1 as a biomarker predicts the prognosis and immunotherapy of breast invasive carcinoma patients

Invasive breast carcinoma(BRCA)is associated with poor prognosis and high risk of mortality.Therefore,it is critical to identify novel biomarkers for the prognostic assessment of BRCA.Methods:The expression data of polo-like kinase 1(PLK1)in BRCA and the corresponding clinical information were extracted from TCGA and GEO databases.PLK1 expression was validated in diverse breast cancer cell lines by quantitative real-time polymerase chain reaction(qRT-PCR)and western blotting.Single sample gene set enrichment analysis(ssGSEA)was performed to evaluate immune infiltration in the BRCA microenvironment,and the random forest(RF)and support vector machine(SVM)algorithms were used to screen for the hub infiltrating cells and calculate the immunophenoscore(IPS).The RF algorithm and COX regression model were applied to calculate survival risk scores based on the PLK1 expression and immune cell infiltration.Finally,a prognostic nomogram was constructed with the risk score and pathological stage,and its clinical potential was evaluated by plotting calibration charts and DCA curves.The application of the nomogram was further validated in an immunotherapy cohort.Results:PLK1 expression was significantly higher in the tumor samples in TCGA-BRCA cohort.Furthermore,PLK1 expression level,age and stage were identified as independent prognostic factors of BRCA.While the IPS was unaffected by PLK1 expression,the TMB and MATH scores were higher in the PLK1-high group,and the TIDE scores were higher for the PLK1-low patients.We also identified 6 immune cell types with high infiltration,along with 11 immune cell types with low infiltration in the PLK1-high tumors.A risk score was devised using PLK1 expression and hub immune cells,which predicted the prognosis of BRCA patients.In addition,a nomogram was constructed based on the risk score and pathological staging,and showed good predictive performance.Conclusions:PLK1 expression and immune cell infiltration can predict post-immunotherapy prognosis of BRCA patients.

Invasive breast carcinoma with osteoclast-like stromal giant cells:A case report

BACKGROUND Invasive breast carcinoma with osteoclast-like stromal giant cells(OGCs) is an extremely rare morphology of breast carcinomas.To the best of our knowledge,the most recent case report describing this rare pathology was published six years ago.The mechanism controlling the development of this unique histological formation is still unknown.Further,the prognosis of patients with OGC involvement is also controversial.CASE SUMMARY We report the case of a 48-year-old woman,who presented to the outpatient department with a palpable,growing,painless mass in her left breast for about one year.Sonography and mammography revealed a 26.5 mm ×18.8 mm asymmetric,lobular mass with circumscribed margin and the Breast Imaging Reporting and Data System was category 4C.Sono-guided aspiration biopsy revealed invasive ductal carcinoma.The patient underwent breast conserving surgery and was diagnosed with invasive breast carcinoma with OGCs,grade Ⅱ,with intermediate grade of ductal carcinoma in situ(ER:80%,3+,PR:80%,3+,HER-2:negative,Ki 67:30%).Adjuvant chemotherapy and post-operation radiotherapy were initiated thereafter.CONCLUSION As a rare morphology of breast cancer,breast carcinoma with OGC occurs most often in relatively young women,has less lymph node involvement,and its occurrence is not racedependent.

Fibromatosis-like metaplastic carcinoma of the breast:Two case reports

BACKGROUND Fibromatosis-like metaplastic carcinoma is classified as a rare type of metaplastic carcinoma of the breast by the 2012 WHO pathological and genetic classification criteria for breast tumors,which takes hyperplastic spindle cells as the main component and is often misdiagnosed as benign stromal proliferative lesions or benign mesenchymal tumors of the breast because of its mild morphology.Here,we collected the clinical data of 2 cases of fibromatosis-like metaplastic carcinoma of the breast and performed pathomorphological observation and immunohistochemical staining of the surgically resected specimens.According to the clinical features,imaging features,immunophenotype,diagnosis and differential diagnosis of 2 cases of fibromatosis-like metaplastic carcinoma of the breast,it was further differentiated.CASE SUMMARY Case 1:A 56-year-old postmenopausal female was admitted due to"right breast mass for over 1 year and local ulceration for over 1 mo".Physical examination showed a mass with a diameter of 4.5 cm×5.5 cm palpable at 2.5 cm from the nipple at 1 o'clock in the right breast.The skin on the surface of the mass ruptured about 3 cm,with a small amount of exudation and bleeding,less clear boundary,hard texture,fair activity,without obvious tenderness.No obvious abnormality was palpable in the left breast.No enlarged lymph nodes were palpable in the bilateral axillae and bilateral supraclavicular region.After removing the mass tissue,it was promptly sent to the pathology department for examination.Case 2:Female,52-years-old,premenopausal,admitted due to"right breast mass for more than 3 mo".Physical examination showed a 4.0 cm×4.0 cm diameter mass palpable at 2.0 cm of the nipple in the lower outer 7 o'clock direction of the right breast,with less clear boundary,hard texture,fair activity,no significant tenderness,no palpable significant abnormalities in the left breast,and no palpable enlarged lymph nodes in the bilateral axillae and bilateral supraclavicular region.The mass was resected and sent for pathological examination.Postoperative pathological examination revealed fibromatosis-like metaplastic carcinoma of the breast in both patient 1 and patient 2.No systemic therapy and local radiotherapy were performed after surgery,and no tumor recurrence or metastasis was observed.CONCLUSION Fibromatosis-like metaplastic carcinoma of the breast is a rare subtype of metaplastic carcinoma that is often misdiagnosed,and the diagnosis relies on medical history collection,complete sampling,and full use of immunohistochemical assessment.The risk of lymph node and distant metastasis is low,and the current treatment is based on complete surgical resection.The efficacy of systemic radiotherapy and chemotherapy is not clear.

Nasopharyngeal carcinoma with synchronous breast metastasis:A case report

BACKGROUND Recent reports have described cases of metachronous breast metastasis in patients with nasopharyngeal carcinoma.However,no similar cases of synchronous breast metastasis have been reported,and evidence that can be used to support the clinical diagnosis of stage IV nasopharyngeal carcinoma in patients with concurrent breast metastasis remains lacking.Therefore,additional evidence is required to elucidate the clinical characteristics of this condition and aid in the development of optimal management strategies.CASE SUMMARY We report the case of a 46-year-old woman who visited our hospital with a right breast mass as the first symptom.The first pathological biopsy report suggested triple-negative breast invasive carcinoma.Subsequent imaging revealed a nasopharyngeal mass.Further puncture biopsy of the nasopharyngeal mass,molecular pathological Epstein–Barr virus in situ hybridization,and immunohistochemistry confirmed the diagnosis of nasopharyngeal carcinoma with breast metastasis.The patient did not undergo a mastectomy and achieved complete remission after chemotherapy and radiotherapy.She continued to receive oral chemotherapy as maintenance therapy and experienced no recurrence or metastasis during the 6-month follow-up period.CONCLUSION This case report suggests that breast specialists should carefully rule out secondary breast cancers when diagnosing and treating breast masses.Furthermore,clinicians should aim to identify the pathological type of the tumor to obtain the most accurate diagnosis and prevent excessive diagnosis and treatment.

Clinicopathologic and molecular characteristics of 44 patients with pure secretory breast carcinoma

Objective: Secretory breast carcinoma(SBC) is a rare type of breast malignancy, accounting for less than 0.02% of all infiltrating breast malignancies. The pure SBC, a type of SBC without another type of breast malignant neoplasm, is particularly rare. This study aimed to investigate the clinicopathologic and molecular features of pure SBC.Methods: The main pathological parameters such as estrogen receptor(ER), progesterone receptor(PR), and human epithelial growth factor receptor 2(C-erbB-2) were detected by immunohistochemistry(IHC), and the clinicopathologic and prognostic difference were compared with invasive ductal carcinoma(IDC). Fluorescent in situ hybridization(FISH) and reverse transcription polymerase chain reaction(RT-PCR) was performed to identify the ETV6-NTRK3 rearrangement of SBC.Results: We found that the positivity rates of ER, PR, C-erbB-2, p53, and S-100 were 47.7%(21/44), 52.3%(23/44), 36.4%(16/44), 27.3%(12/44), and 95.5%(42/44), respectively, which were higher than those reported in previous studies. Special periodic acid-Schiff analysis was performed in 36 patients, and the value of the Ki-67 index ranged from 1% to 50%(mean value:10%). Interestingly, most patients with pure SBC harbored an ETV6-NTRK3 rearrangement with an 88.6%(39/44) expression rate. Compared with IDC, the tumor size of most patients with SBC was larger than 2 cm(P = 0.024). Ultrasound showed benign lesions, and the total misdiagnosis rate was higher(P = 0.020). Although the pathological classification was mostly triple-negative breast cancers(P = 0.036), there was less metastasis(P = 0.029), and the overall prognosis was better than that of the IDC group.Conclusions: Although axillary lymph node metastasis, local recurrence, or distant metastasis may occur, SBC is also considered an indolent neoplasm with a good prognosis. Once diagnosed, surgical treatment should be performed as soon as possible,followed by appropriate adjuvant chemotherapy, irradiation, and endocrine therapies.

Adenoid cystic carcinoma of breast: Recent advances

Adenoid cystic carcinoma(ACC) of the breast is a rare special subtype of breast cancer characterized by the presence of a dual cell population of luminal and basaloid cells arranged in specific growth patterns. Most breast cancers with triple-negative, basal-like breast features(i.e., tumors that are devoid of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 expression, and express basal cell markers) are generally high-grade tumors with an aggressive clinical course. Conversely, while ACCs also display a triple-negative, basal-like phenotype, they are usually low-grade and exhibit an indolent clinical behavior. Many discoveries regarding the molecular and genetic features of the ACC, including a specific chromosomal translocation t(6;9) that results in a MYB-NFIB fusion gene, have been made in recent years. This comprehensive review provides our experience with ACC of the breast, as well as an overview of clinical, histopathological, and molecular genetic features.

Diffusion-tensor imaging as an adjunct to dynamic contrastenhanced MRI for improved accuracy of differential diagnosis between breast ductal carcinoma in situ and invasive breast carcinoma

Objective： To determine the value of diffusion-tensor imaging （DTI） as an adjunct to dynamic contrastenhanced magnetic resonance imaging （DCE-MRI） for improved accuracy of differential diagnosis between breast ductal carcinoma in situ （DCIS） and invasive breast carcinoma （IBC）. Methods： The MRI data of 63 patients pathologically confirmed as breast cancer were analyzed. The conventional MRI analysis metrics included enhancement style, initial enhancement characteristic, maximum slope of increase, time to peak, time signal intensity curve （TIC） pattern, and signal intensity on FS- T2WI. The values of apparent diffusion coefficient （ADC）, directionally-averaged mean diffusivity （D^vg）, exponential attenuation （EA）, fractional anisotropy （FA）, volume ratio （VR） and relative anisotropy （RA） were calculated and compared between DCIS and IBC. Multivariate logistic regression was used to identify independent factors for distinguishing IBC and DCIS. The diagnostic performance of the diagnosis equation was evaluated using the receiver operating characteristic （ROC） curve. The diagnostic efficacies of DCE- MRI, DWI and DTI were compared independently or combined. Results： EA value, lesion enhancement style and TIC pattern were identified as independent factor for differential diagnosis of IBC and DCIS. The combination diagnosis showed higher diagnostic efficacy than a single use of DCE-MRI （P=0.02）, and the area of the curve was improved from 0.84 （95% CI, 0.67-0.99） to 0.94 （95% CI, 0.85-1.00）. Conclusions： Quantitative DTI measurement as an adjunct to DCE-MRI could improve the diagnostic performance of differential diagnosis between DCIS and IBC compared to a single use of DCE-MRI.

Lymphoepithelioma-like carcinoma of the breast presenting as breast abscess

Lymphoepithelioma-like carcinoma(LELC) is a rare type of neoplasm in which only twenty cases have been reported in the breast. This type of tumor can be difficult to distinguish from other breast tumors particularly medullary carcinoma and lymphoma in the breast. We present a case of LELC of the breast presenting as an abscess along with a review of the literature. This is the 21 st reported case of LELC of the breast and the first case to present as an abscess. Her clinical picture could have been mistaken for other infectious or inflammatory diseases. Given the potential for favorable outcome, early detection and general knowledge of this neoplasm are essential to expedite treatment for this rare tumor type.

Breast-conserving therapy and modified radical mastectomy for primary breast carcinoma:a matched comparative study

Background- To compare two types of therapy for primary breast carcinoma, breast-conserving therapy （BCT） and modified radical mastectomy （MRM）, in a matched cohort study. Methods： A series of 1,746 patients with primary breast cancer treated with BCT or MRM in a single Chinese institute between January 2000 and February 2009 were analyzed retrospectively to compare their outcomes with respect to the incidence of local recurrence （LR）, distant metastasis, and survival. The patients were matched with regard to age at diagnosis, spreading to axillary lymph nodes, hormone receptor status, the use of neoadjuvant chemotherapy and maximal tumor diameter. The match ratio was 1：1, and each arm included 873 patients. Results： The median follow-up period was 71 months. The 6-year disease-free survival （DFS） and 6-year distant disease-free survival （DDFS） rates differed significantly between two groups. The 6-year local recurrence-free survival （LRFS） rates were 98.2% [95% confidence interval （CI）： 0.973-0.989] in the BCT group and 98.7% （95% CI： 0.980-0.994） in the MRM group （P=0.182）, respectively. DFS rates in BCT and MRM groups were 91.3% （95% CI： 0.894-0.932） and 86.3% （95% CI： 0.840-0.886） （P〈0.001）, respectively, whereas the DDFS rates in BCT and MRM groups were 93.6% （95% CI： 0.922-0.950） and 87.7% （95% CI： 0.854-0.900） （P〈0.001）, respectively. Conclusions： BCT in eligible patients is as effective as MRM with respect to local tumor control, DFS and DDFS, and may result in a better outcome than MRM in Chinese primary breast cancer patients.

Vascular Endothelial Growth Factor Expression in Invasive Ductal Carcinoma of Breast

Objective： To detect the expression of VEGF and MVD count in invasive ductal carcinoma of breast to clarify the association of VEGF expression and MVD count with the clinicopathologic features. Methods： The expressions of VEGF, ER, PR, C-erbB-2 and MVD count in 88 cases of invasive ductal carcinoma of breast were examined by immunohistochemistry staining （SP-method）. Results： Sixty-two out of the eighty-eight specimens of breast carcinoma （70.45%） showed positive expression of VEGF. The positive rate of VEGF in cases with lymph node metastasis was higher than that without lymph node metastasis （P〈0.05）. The positive rate of VEGF in stage IIb-Ⅲ was higher than that in stage Ⅰ-Ⅱa （P〈0.05）. The positive rate of VEGF in C-erbB-2 positive group was higher than that in C-erbB-2 negative group （P〈0.05）. Higher expression of VEGF was observed in cases with higher tissue differentiation degree （P〈0.05）. Also, significant higher MVD count was observed in cases with higher tissue differentiation degree （P〈0.01）. The MVD count increased significantly with the increase of the expression of VEGF （P〈0.01）. Conclusion： The result of this study suggested that in invasive ductal carcinoma of breast, angiogenesis and metastasis were mediated mainly by VEGF. The expression of VEGF and MVD might be reference predictors for the biological behavior of breast carcinoma. The antiangiogenic therapy which used VEGF as a target would become a new method to treat patients who were C-erbB-2 positive in the future.

Papillary carcinoma of breast: Minireview

The term "intracystic papillary ductal carcinoma in situ " constitutes only 0.5% to 1% of all breast cancers.It is usually seen in postmenopausal age group.Herein,we are presenting a minireview about this unusual breast malignancy usually difficult to diagnose on clinical grounds and highlighting modalities of diagnosis and management.

Tumor characteristics of ductal carcinoma in situ of breast visualized on [F-18] fluorodeoxyglucose-positron emission tomography/computed tomography: Results from a retrospective study

AIM To clarify clinicopathological features of ductal carcinoma in situ(DCIS) visualized on [F-18] fluorodeoxyglucosepositron emission tomography/computed tomography(FDG-PET/CT).METHODS This study retrospectively reviewed 52 consecutive tumors in 50 patients with pathologically proven pure DCIS who underwent [F-18] FDG-PET/CT before surgery. [F-18] FDG-PET/CT was performed after biopsy in all patients. The mean interval from biopsy to [F-18] FDGPET/CT was 29.2 d. [F-18] FDG uptake by visual analysis and maximum standardized uptake value(SUVmax) was compared with clinicopathological characteristics.RESULTS[F-18] FDG uptake was visualized in 28 lesions(53.8%) and the mean and standard deviation of SUVmax was 1.63 and 0.90. On univariate analysis, visual analysis and the SUVmax were associated with symptomatic presentation(P = 0.012 and 0.002, respectively), palpability(P = 0.030 and 0.024, respectively), use of core-needle biopsy(CNB)(P = 0.023 and 0.012, respectively), ultrasound-guided biopsy(P = 0.040 and 0.006, respectively), enhancing lesion ≥ 20 mm on magnetic resonance imaging(MRI)(P = 0.001 and 0.010, respectively), tumor size ≥ 20 mm on histopathology(P = 0.002 and 0.008, respectively). However, [F-18] FDG uptake parameters were not significantly associated with age, presence of calcification on mammography, mass formation on MRI, presence of comedo necrosis, hormone status(estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2), and nuclear grade. The factors significantly associated with visual analysis and SUVmax were symptomatic presentation(P = 0.019 and 0.001, respectively), use of CNB(P = 0.001 and 0.031, respectively), and enhancing lesion ≥ 20 mm on MRI(P = 0.001 and 0.049, respectively) on multivariate analysis.CONCLUSION Although DCIS of breast is generally non-avid tumor, symptomatic and large tumors(≥ 20 mm) tend to be visualized on [F-18] FDG-PET/CT.

Pure Mucinous Carcinoma of the Breast:a Clinicopathologic Analysis with 56 Patients

Objective To assess recent trends and prognostic features in the treatment of pure mucinous carcinoma(PMC) of the breast.Methods Fifty-six patients diagnosed with PMC of the breast in our hospital from December 1982 to June 2008 were included.We evaluated the general information and tumor characteristics of the patients,examined the relationship between these factors and prognosis.Fisher's exact test was applied to analyze tumor characteristics.Results The mean age of the patients was 53.7 years.The majority of the patients presented with early stage disease.Tumor size was found not a significant prognostic factor in this study.Mean follow-up period was 39 months and no breast cancer-related deaths were identified in the patient cohort.Conclusions PMC of the breast has a favorable prognosis.Tumor size does not appear to significantly impact survival.

Subcutaneous and breast metastasis from asymptomatic gallbladder carcinoma

BACKGROUND:Though gallbladder carcinoma is asso- ciated with early lymphatic and hematogenous spread, the only common extra-abdominal site of metastasis is lung.Gallbladder carcinoma metastasizing to breast and subcutaneous tissue is not known. METHOD:This report describes an interesting and unusual case of asymptomatic gallbladder carcinoma presenting with subcutaneous and breast metastasis. RESULTS:A 42-year-old woman presented with multiple subcutaneous nodules over the abdominal wall,anterior chest wall,back and in bilateral breasts.Fine needle aspiration cytology(FNAC)of these nodules revealed metastatic adenocarcinoma.The patient was investigated for a primary neoplasm.An ultrasound of the abdomen followed by a contrast-enhanced CT scan showed a growth in gallbladder,infiltrating the liver with multiple hepatic metastases.CT-guided FNAC from the growth in the gallbladder revealed adenocarcinoma.She was diagnosed as a case of metastatic adenocarcinoma of the gallbladder and palliative combination chemotherapy with gemcitabine and carboplatin was given.But she developed jaundice and deteriorated dramatically in a short span of time.No specific therapy could be started and she was given supportive treatment.She died within three weeks of diagnosis due to hepatic encephalopathy. CONCLUSIONS:This report highlights an unusual metastasis of gallbladder carcinoma to the breast and subcutaneous tissue presenting as multiple lesions,which has never been reported in the English literature.These were unknown sites of metastasis for carcinoma of the gallbladder.Moreover,bilateral multiple metastatic lesions to breast are also very rare.

Ultrasonographic features of breast ductalcarcinoma in situ

Objective The aims of this study were to analyze ultrasound features of breast ductal carcinoma in situ(DCIS) and to evaluate the value of ultrasonography(US) in early diagnosis of DCIS.Methods From July 2013 to March 2015,180 patients with histologically proven DCIS were evaluated.US features recorded included the size,shape,margins,internal echogenicity,microcalcifications,posterior echogenicity,and blood supply.The data were analyzed and compared with mammographic and histologic findings.Results Among 180 cases of DCIS,168 patients had positive findings on US;the lesions were divided into 3 categories:(1) hypoechoic lesions with or without microcalcifications(n=94);(2) hypoechoic dilated ducts with or without microcalcifications(n=59);(3) microcalcifications alone without any other findings(n=15).Of the 180 lesions,microcalcifications were demonstrated by mammography in 128(71%);among these 128 lesions,90 were identified with microcalcifications on US.Only 80 cases(44%) manifested as masses or asymmetric densities on mammography.The diagnostic accuracy of US and mammography was 67%(120/180) and 69%(124/180),respectively,which can be improved to 80%(144/180) if US is combined with mammography.Conclusion US can be used as an important tool in diagnosis of DCIS.The combination of US and mammography can improve the diagnostic accuracy of breast DCIS.

Solid neuroendocrine breast carcinoma:mammographic and sonographic features in thirteen cases

This study aimed to determine and quantitate the mammographic and sonographic characteristics in 13 cases of solid neuroendocrine breast carcinoma(NEBC) and to analyze the association of radiological findings with the clinical and histopathologic findings.The clinical data and imaging findings of 13 female patients with histologically confirmed solid NEBC were reviewed.Imaging data were evaluated by two radiologists for a consensual diagnosis.All patients presented with one palpable mass;only 1 experienced occasional breast pain,and 5 complained of fluid discharge.In 7 patients,the masses were firm and mobile.Regional lymph node metastasis was noted in only 1 patient.For the 10 patients who underwent mammography,6 had a mass,1 had clustered small nodules with clustered punctuate microcalcifications,2 had asymmetric focal density,and 1 had solitary punctuate calcification.Most of the masses had irregular shape with indistinct or microlobulated margins.For the 9 patients who underwent ultrasonography(US),9 masses were depicted,all of which were hypoechoic,mostly with irregular shape and without acoustic phenomena.Different types of acoustic phenomena were also identified.One patient had developed distant metastases during follow-up.NEBC has a variety of presentations,but it is mostly observed on mammograms as a dense,irregular mass with indistinct or microlobulated margins.Sonographically,it typically presents as an irregular,heterogeneously hypoechoic mass with normal sound transmission.Histories of nipple discharge and calcification observed using imaging are not rare.

Breast adenoid cystic carcinoma arising in microglandular adenosis:A case report and review of literature

BACKGROUND Breast adenoid cystic carcinoma(AdCC)is a rare invasive carcinoma composed of epithelial and myoepithelial cells.Microglandular adenosis(MGA)is a rare benign proliferative lesion consisting of small,uniform,and round glands formed by a single layer of epithelial cells and basement membrane without a myoepithelial cell layer.MGA may progress to atypical MGA and carcinoma arising in MGA.Among various invasive carcinomas from MGA,AdCC has been rarely reported.Here,we report a case of AdCC arising in MGA.CASE SUMMARY A 59-year-old woman was diagnosed with a newly developed density on a routine mammogram.The density was similar to or slightly lower than that of the breast parenchyma.Sonography showed an irregular mass with a slightly higher echo than that of fat.Magnetic resonance imaging showed an irregular mass with a similar T1 signal intensity and a slightly higher T2 signal intensity compared to muscles or the breast parenchyma.The lesion showed heterogeneous internal enhancement with an initially slow and delayed persistent enhancing pattern.Microscopically,the tumor was composed of invasive AdCC,in situ AdCC,and MGA.AdCC is composed of basaloid and ductal epithelial cells forming cribriform or solid sheets,or haphazardly scattered small cribriform or tubular glands.MGA showed small glands with a single epithelial lining and retained lumen.S-100 staining was strongly positive in MGA area.The patient underwent breast-conserving surgery with sentinel lymph node biopsy.CONCLUSION Breast AdCC arising in MGA showed unique imaging findings that was different from usual invasive cancer.

DUCTAL CARCINOMA IN SITU OF THE BREAST

Objective: To investigate the clinical characteristics, treatment and prognosis of ductal carcinomain situ (DCIS) of the breast. Methods: Clinicopathological and follow-up data were collected in 52 patients with DCIS. Results: The clinic data showed that 50 patients had signs of breast lumps or/and nipple discharges, 2 patients presented abnormal mammography; 2 patients had lymph node involved; and 14 patients were accompanied with intraductal papillomatosis. All patients were received surgical therapy. The follow-up data showed 1 patient locally recurred after lumpectomy, and was underwent mastectomy again, then cured. There were no patients died of DCIS. Conclusion: Mastectomy should be a standard surgical mode, and the prognosis of DCIS was favorable, but mammography for screening of asymptomatic women should be strengthened to find DCIS.

Chinese Herbal Medicine Combined Conventional Chemotherapy Regimens in Advanced Recurrent Breast Mammary Carcinoma

Purpose: Aiming at starting the ball rolling and contributing humble effort to promoting traditional Chinese medicine, we report one successful case of “GP” regimen of combining chemotherapy with traditional Chinese medicine decoction (“lung description”) for breast cancer with lung and bone metastases. Patients and Methods: A second-line chemotherapy regimen of GP (cisplatin + gemcitabine) was applied. In the meantime, we administered Chinese herbal medicine (Fei Decoction, mixed with a variety of effective herbal components) to help her recover from the poor condition. Results: The tumor markers (CEA, CA15-3) had dramatically decreased to the normal range. Both lung and bone metastatic sites reduced according to CT and ECT imaging, and this patient felt free from the complaint of pulmonary and cardiac discomfort. The quality of life has been greatly improved, and the PFS (Progression-Free-Survival) and TTP (Time-to-Progression) have been prolonged from the onset to date. Conclusions: In the course of this combined treatment, it has been shown that Chinese herbal medicine played an important role in the therapy of breast mammary carcinoma. Therefore, Chinese herb may turn out to be an additional choice with its better benefits and tolerability in the treatment of recurrent breast mammary carcinoma.
