BACKGROUND Clinical reports of multiple primary malignant tumors(MPMTs)in the digestive system are increasing.In China,although the survival rate of patients with MPMTs is increasing,the quality of life is very low.Many patients have reached the advanced stage when the second primary tumor is found,resulting in no early intervention and treatment.This is due to the misunderstanding of MPMTs by clinicians,who treat such tumors as metastases.Therefore,before a patient has a second primary tumor,doctors should understand some common combinations of digestive system MPMTs to provide clinical guidance to the patient.AIM To explore the high incidence combination of digestive system MPMTs under heterochronism and synchronization.METHODS A total of 1902 patients with MPMTs at Peking Union Medical College Hospital were analyzed retrospectively.They were divided into metachronous MPMT and synchronous MPMT groups,and then the high incidence combinations of the first primary cancer and the second primary cancer in metachronous cancer and synchronous cancer were sorted.Sex and age differences between metachronous and synchronous tumors were tested by the chi square test and t test,respectively.A P value<0.05 was considered as statistically significant,and SPSS version 26.0(SPSS Inc.,Chicago,Illinois,United States)was used for statistical analysis.RESULTS Among the 1902 patients with MPMTs confirmed by pathology,1811(95.2%)cases were secondary primary cancers,89(4.7%)cases were tertiary primary cancers,and 2(0.1%)cases were quaternary primary cancers.Most(88.2%)of the secondary primary cancers were identified as metachronous multiple primary cancers six months after diagnosis of the first primary cancer.The top ten most common MPMTs in the first primary cancer group ranged from high to low as follows:Breast cancer,thyroid cancer,nonuterine cancer,lung cancer,colon cancer,kidney cancer,uterine cancer,bladder cancer,rectal cancer,and gastric cancer.The highest incidence rate of the first primary cancer in male metachronous cancer was lung cancer(11.6%),the highest incidence rate of the second primary cancer was still lung cancer(24.9%),the highest incidence rate of the first primary cancer in female metachronous cancer was breast cancer(32.7%),and the highest incidence rate of the second primary cancer was lung cancer(20.8%).Among them,breast cancer,nonuterine cancer and uterine cancer were female-specific malignant tumor types,and thyroid cancer also accounted for 79.6%of female patients.The top five metachronous cancer combinations,independent of female-specific malignant tumor types and thyroid cancer,were colon cancer and lung cancer(26 cases),kidney cancer and lung cancer(25 cases),rectal cancer and lung cancer(20 cases),gastric cancer and lung cancer(17 cases),and bladder cancer and lung cancer(17 cases).The most common synchronous cancer combination was colon cancer and rectal cancer(15 cases).CONCLUSION Screening for lung cancer should be performed six months after the detection of colon cancer while rectal cancer screening should be performed within six months. 展开更多

AIM: To describe the histopathologic and clinical features of eyelid tumor cases from Tianjin Eye Hospital during 2002 to 2015. METHODS: In this retrospective study, a total of 2228 cases of eyelid tumors with pathologic diagnoses were enrolled. The eyelid tumors were classified into three groups according to tumor origin: epidermal, adnexal and miscellaneous, including melanocytic, neural and vascular lesions. Inflammatory tumor-like lesions were excluded. The clinical characteristics of the eyelid tumors were analyzed, including age, gender and lesion location. RESULTS: Most eyelid tumors were epidermal in origin(1080, 48.5%), followed by miscellaneous(885, 39.7%) and adnexal tumors(263, 11.8%). Among all the tumors, 292(13.1%) were malignant lesions, 1910(85.7%) benign and 26(1.1%) premalignant lesions. Most malignant tumors originated from epidermal cells(60.0%), followed by adnexal cells(34.6%). The most common malignant tumors were basal cell carcinomas(56.5%) followed by sebaceous carcinoma(34.6%), squamous cell carcinomas(3.8%) and lymphoma/plasmocytoma(1.7%). The benign and premalignant eyelid lesions mostly originated from epidermal cells(46.4%) followed by miscellaneous cell sources(45.2%), including melanocytic nevus(33.8%), seborrheic keratosis(13.7%), squamous cell papilloma(13.0%) and epidermal cysts(11.5%). CONCLUSION: Eyelid tumors are mostly epithelial in origin. Benign tumors are significantly more common than malignant tumors with an obvious female predominance, and the most frequent malignant tumor are basal cell carcinoma, sebaceous carcinoma and squamous cell carcinomas. The tumor clinical features varied among the different subtypes. 展开更多

It has long been recognized that some cases are familial. The majority of these tumors are benign, and the only absolute criterion for malignancy is the presence of metastases at sites where chromaffin tissue is not usually found. Some tumors show gross local invasion and recurrence, which may indeed kill the patient, but this does not necessarily associate with metastatic potential. Here, we report a case of vertebral metastatic paraganglioma that occurred 19 months after the patient had undergone partial cystectomy for urinary bladder paraganglioma. We believe this to be a rarely reported bone metastasis of paraganglioma arising originally within the urinary bladder. In this report, we also provide a summary of the general characteristics of this disease, together with progress in diagnosis, treatment, and prognosis. 展开更多

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. 展开更多

BACKGROUND Esophageal adenoid cystic carcinoma(EACC)is an exceedingly rare malignant tumor of the esophagus,posing significant challenges in the clinic.CASE SUMMARY This report detailed the case of a 72-year-old male whose diagnosis of EACC was confirmed through postoperative histopathological examination.The patient underwent thoracoscopy-assisted radical resection of the esophageal tumor,coupled with lymph node dissection.Pathological findings revealed an adenoid cystic carcinoma infiltrating the entire layer of the muscularis propria,locally extending into the outer membrane of the esophageal fiber,involving the cardia and exhibiting no lymph node metastasis.The patient’s condition was classified as primary EACC,T3N0M0,per the American Joint Committee on Cancer(2017;8th edition).One month after surgery,the patient received postoperative adjuvant radiation therapy.CONCLUSION In addressing the rarity and high potential for biopsy misdiagnosis of EACC,this study delved into its diagnostic methods and treatment. 展开更多

Introduction: Squamous cell carcinoma of the conjunctiva is one of the most common malignancies in the elderly. Purpose: To describe the specific aspects of squamous cell carcinoma of the conjunctiva and to determine the therapeutic modalities. Materials and Methods: Descriptive cross-sectional retrospective study carried out at the University Hospital Center of Bouake over a period of 9 years (From January 2015 to December 2023). We identified all malignant oculo-adnexal and orbital tumors whose histopathological diagnosis was confirmed;monitoring the sorting of squamous cell carcinomas of the conjunctiva among these cancers and studying the different parameters linked to them. Results: The average age of patients is 44.3 years. Male predominance with a sex ratio of 1.12. HIV was the majority ATCD with 64.7%. The main reason for consultation was exophthalmos (36.11%). The average consultation time was 10 months 13 days. Invasive differentiated conjunctival squamous cell carcinoma was predominant at 55.56%. Enucleation was the most performed surgical method. Conclusion: Squamous cell carcinoma of the conjunctiva is a malignant ocular tumor of the elderly whose frequency increases in young adults infected with HIV-AIDS. Invasive differentiated forms are increasingly encountered, limiting treatment to mutilating surgery. 展开更多

BACKGROUND Neuroendocrine neoplasms are rarely located in the gallbladder(GB),and carcinoid syndrome is exceedingly rare in patients with GB neuroendocrine neoplasms.CASE SUMMARY We report a case of GB neuroendocrine carcinoma(GB-NEC)in a 65-year-old man,who presented with flushing for 2 mo.Pathological specimens of the flushed skin revealed that mucin was deposited between the collagen bundles in the dermis.Computed tomography and magnetic resonance imaging indicated neoplasm in the GB with liver invasion and enlarged lymph nodes in the portacaval space.High fluorodeoxyglucose uptake was detected in lymph nodes in the portacaval space,but distant metastasis was not seen by positron emission tomography.Ultrasound-guided needle biopsy of the GB neoplasm was suggestive of high-grade NEC.Because of the functional characteristics of poorly differentiated NEC,en bloc cholecystectomy,resection of hepatic segments IVb and V,pancreaticoduodenectomy,and regional lymphadenectomy were performed.A diagnosis of poorly differentiated NEC was made by pathological findings and immunohistochemical staining data.Ki-67 index was>80%.The patient refused adjuvant therapy and passed away in the 7th month.CONCLUSION Distinctive manifestation combined with imaging helps make correct preoperative diagnosis.Radical surgery and adjuvant chemotherapy might improve prognosis. 展开更多

BACKGROUND Squamous cell carcinoma(SCC)of the nail bed is a poorly reported malignant subungual tumor.Because it presents with nonspecific symptoms and signs,it is frequently misdiagnosed by dermatologists or surgeons.A delay in diagnosis and/or wrong treatment might increase the possibility of disease progression.Thus,new perspectives are needed to assist dermatologists and surgeons with diagnosing and treating SCC.This rare case presented with a 2-year delay in the diagnosis of SCC teaches a valuable lesson.CASE SUMMARY A 62-year-old female presented with a non-healing subungual growth in the nail bed of the right middle finger for 2 years.The lesion was first medicated with iodine by the patient herself without any relief.Twenty months later,a dermatologist diagnosed the lesion as paronychia and treated it with nail avulsions repeatedly with no obvious alleviation.A lesionectomy confirmed the lesion was SCC.An extended excision of the tumor with amputation of the distal interphalangeal joint was subsequently performed.A biopsy of sentinel lymph nodes was negative.Due to the result of preoperative positron emission tomography-computed tomography scanning,sweeping of axillary lymph nodes was considered dispensable and was skipped.At the 2-year follow-up,the patient showed a quick recovery and no sign of recurrence.CONCLUSION Our successful diagnosis and treatment of the case highlights the need for additional attention to long-standing non-healing lesions of the nail bed and the necessity for discreet evaluation and customization of surgical interventions. 展开更多

BACKGROUND Only a few cases of carcinoma ex pleomorphic adenoma arising in the submandibular gland have ever been reported,all with a poor prognosis. The standard treatment for salivary gland carcinoma ex pleomorphic adenoma is surgical resection combined with postoperative radiotherapy,but the necessity of chemotherapy as well as the most appropriate treatment regimen for patients with distant metastasis after radiotherapy remains controversial.CASE SUMMARY This report presents the case of a 73-year-old woman who suffered submandibular gland carcinoma ex pleomorphic adenoma. She accepted surgery to remove the mass; she was found to have lung metastasis after radiotherapy.Her condition was controlled by chemotherapy with liposomal doxorubicin plus cisplatin.CONCLUSION The positive clinical outcome in the patient reveals that this chemotherapy regimen may be an alternative treatment for such a condition. 展开更多

BACKGROUND Mucoepidermoid carcinoma of the lung is a rare malignant tumor,accounting for 0.1%–0.2%of all lung malignancies.It is a primary salivary gland tumor of the lung.Surgical resection is the primary treatment for pulmonary mucoepidermoid carcinoma,for which there has been no standardized treatment strategy.This article reports a case of a young woman with pulmonary mucoepidermoid carcinoma with hemoptysis as the first symptom.CASE SUMMARY A 24-year-old female patient presented with"4 d of hemoptysis"as the chief complaint.She had no special history and denied any smoking or drinking history.Physical examination revealed that the vital signs were stable and scattered small wet rales were heard in the left lung.After admission,the lung tumor markers were checked,and no abnormalities were found.After completing the bronchoscopy,a spherical lesion was observed at the main bronchus 1.5 cm away from the protubercle,with obvious pulsation and little blood seepage on the surface,and histopathological biopsy results showed acute and chronic inflammation.She was transferred to the Department of Thoracic Surgery for surgical treatment on the 16th day after admission.After exclusion of surgical conjunctures,the patient underwent resection of the tumor in the left main bronchus with single-pore video-assisted thoracic surgery on the 19th day after admission.The postoperative histopathological biopsy results showed mucoepidermoid carcinoma of the lung.The patient and her family refused to complete genetic testing and she was discharged from the hospital on the 8th day after surgery.During the follow-up period,the patient experienced shortness of breath after feeling active and had no special discomfort.CONCLUSION We have documented a case of moderately differentiated mucoepidermoid lung cancer with hemoptysis as the first symptom to improve clinicians'understanding of the disease and provide a new dimension of thinking for its future diagnosis and treatment. 展开更多
