BACKGROUND Anaplastic lymphoma kinase(ALK)-positive large B-cell lymphoma(LBCL)is an aggressive and rare variant of diffuse LBCL.Herein,we report an uncommon case of stage IE extranodal ALK-positive LBCL initially originating in the bulbar con-junctiva.CASE SUMMARY A 63-year-old woman presented with a mass in the left bulbar conjunctiva that had persisted for six months,accompanied by swelling and pain that had per-sisted for 3 d.Eye examination revealed an 8 mm slightly elevated pink mass in the lower conjunctival sac of the left eye.Microscopically,the tumor was com-posed of large immunoblastic and plasmablastic large lymphoid cells with scattered anaplastic or multinucleated large cells.Immunophenotypically,the neoplastic cells were positive for ALK,CD10,CD138,Kappa,MUM1,BOB.1,OCT-2,CD4,CD45,EMA,CD79a,CD38,and AE1/AE3,and negative for CD20,PAX5,Lambda,BCL6,CD30 and all other T-cell antigens.The results of gene rearrangement tests showed monoclonal IGH/IGK/IGL and TCRD rearran-gements.Fluorescence in situ hybridization studies did not reveal any BCL2,BCL6 or MYC rearrangements.Furthermore,Epstein-Barr virus was not detected by in situ hybridization in the lesions.Based on the histopathological and imaging examinations,the neoplasm was classified as stage IE ALK-positive LBCL.No further treatments were administered.At the 6,15,and 21 mo postoperative follow-up visits,the patient was in good condition,without obvious discomfort.This case represents the first example of primary extranodal ALK-positive LBCL presenting as a bulbar conjunctival mass,which is extremely rare and shares morphological and immunohistochemical features with a variety of other neo-plasms that can result in misdiagnosis.CONCLUSION Awareness of the condition presented in this case report is necessary for early and accurate diagnosis and appropriate treatment. 展开更多

Thyroid carcinoma is a complex disease with several types,the most common being well-differentiated and undifferentiated.The latter,“undifferentiated carcinoma”,also known as anaplastic thyroid carcinoma(ATC),is a highly aggr-essive malignant tumor accounting for less than 0.2%of all thyroid carcinomas and carries a poor prognosis with a median survival of 5 months.BRAF gene mutations are the most common molecular factor associated with this type of thyroid carcinoma.Recent advances in targeted biological agents,immuno-therapy,stem cell therapy,nanotechnology,the dabrafenib/trametinib com-bination therapy,immune checkpoint inhibitors(ICI)and artificial intelligence offer novel treatment options.The combination therapy of dabrafenib and tra-metinib is the current standard treatment for patients with BRAF-V600E gene mutations.Besides,the dabrafenib/trametinib combination therapy,ICI,used alone or in combination with targeted therapies have raised some hopes for improving the prognosis of this deadly disease.Younger age,earlier tumor stage and radiotherapy are all prognostic factors for improved outcomes.Ultimately,therapeutic regimens should be tailored to the individual patient based on surveillance and epidemiological data,and a multidisciplinary approach is ess-ential. 展开更多

Background: A number of meningeal neoplastic lesions may radiologically and clinically simulate meningioma, include hemangiopericytomas, solitary fibrous tumors, schwannomas, hematolymphoid lesions, metastases, and others very rarely, also may clinically mimic meningiomas. Case Description: We present the case of A 28-year-old male patient, with no notable medical history, who presented with worsening headaches for 3 months, imbalance, and visual deficits, An initial MRI revealed extra-axial lesion involving the right Parieto-occipital, The tumor was hypointense on T1-weighted MR images, hyperintense signals on T2-weightedMR images, and heterogeneously enhanced suggestive of a meningioma, total resection was achieved, and the histopathological analysis confirmed the diagnosis of an angioblastic meningioma. However, 15 months later, the patient presented with the same initial visual complaints. A subsequent MRI showed lesion recurrence, leading to a second surgical intervention. The histopathological analysis confirmed the diagnosis of an anaplastic xanthoastrocytoma. Conclusion: This represents an unusual location for an anaplastic pleomorphic xanthoastrocytoma, which should broaden the differential diagnosis of extra-axial lesions. 展开更多

Well-differentiated thyroid carcinoma has a favorable prognosis with a 5-year survival rate of over 95%.However,the undifferentiated or anaplastic type accounting for<0.2%,usually in elderly individuals,exhibits a dismal prognosis with rapid growth and disappointing outcomes.It is the most aggressive form of thyroid carcinoma,with a median survival of 5 mo and poor quality of life(airway obstruction,dysphagia,hoarseness,persistent pain).Early diagnosis and staging are crucial.Diagnostic tools include biopsy(fine needle aspiration,core needle,open surgery),high-resolution ultrasound,computed tomography,magnetic resonance imaging,[(18)F]fluoro-D-glucose positron emission tomography/computed tomography,liquid biopsy and microRNAs.The BRAF gene(BRAF-V600E and BRAF wild type)is the most often found molecular factor.Others include the genes RET,KRAS,HRAS,and NRAS.Recent management policy is based on surgery,even debulking,chemotherapy(cisplatin or doxorubicin),radiotherapy(adjuvant or definitive),targeted biological agents and immunotherapy.The last two options constitute novel hopeful management modalities improving the overall survival in these otherwise condemned patients.Anti-programmed death-ligand 1 antibody immunotherapy,stem cell targeted therapies,nanotechnology achievements and artificial intelligence implementation provide novel promising alternatives.Genetic mutations determine molecular pathways,thus indicating novel treatment strategies such as anti-BRAF,anti-vascular endothelial growth factor-A,and anti-epidermal growth factor receptor.Treatment with the combination of the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib has been approved by the Food and Drug Administration in cases with BRAF-V600E gene mutations and is currently the standard care.This neoadjuvant treatment followed by surgery ensures a twoyear overall survival of 80%.Prognostic factors for improved outcomes have been found to be younger age,earlier tumor stage and radiation therapy.A multidisciplinary approach is necessary,and the therapeutic plan should be individu alized based on surveillance and epidemiology end results. 展开更多

BACKGROUND Anaplastic thyroid cancer(ATC)is a rare but aggressive type of thyroid carcinoma.BRAF V600E-mutation,which is found in 10%-50%of ATCs,is associated with poor prognosis.A recent clinical trial reported a substantial clinical benefit of concomitant treatment of dabrafenib(BRAF inhibitor)and trametinib(MEK inhibitor)for treating BRAF V600E-mutant ATC.However,reports on patients with ATC treated with this regimen following surgery are lacking.CASE SUMMARY We report the case of a 63-year-old female patient diagnosed with BRAF V600Emutant ATC.Following three surgeries—total thyroidectomy,total laryngectomy,and neck dissection—she was diagnosed with lung metastasis during follow-up.The metastatic ATC was successfully treated with dabrafenib and trametinib.The patient achieved a complete response at the 32-mo follow-up.CONCLUSION Adjuvant chemotherapy with dabrafenib plus trametinib is efficacious for treatment and prevention of recurrent ATC with BRAF mutation following surgery. 展开更多

BACKGROUND Primary cutaneous anaplastic large cell lymphoma(PC-ALCL)differs from systemic anaplastic large cell lymphoma(sALCL)in cell biological behavior,clinical features,treatment,and outcome.PC-ALCL has been reported to rarely transition into sALCL,but the underlying mechanism is not clear.Here we report such a case with certain characteristics that shed light on this.CASE SUMMARY Herein,we report a 43-year-old male with symptoms of a skin nodule and histologically confirmed PC-ALCL with high expression of Ki-67.After three months of observation,two skin nodules re-appeared with muscle layer involvement and was histologically confirmed as sALCL.Seventeen months after receiving six cycles of CHOP regimen,the patient had pain in the chest and back,cough,shortness of breath,and night sweats.This was confirmed as relapse of sALCL by immunohistochemistry and several organs,such as the lung were involved as shown by positron emission tomography/computed tomography.After four cycles of DICE plus chidamide regimens followed by auto-hematopoietic stem cell transplantation(ASCT),complete remission(CR)duration was achieved for twelve months while the patient was on maintenance with chidamide(20 mg)pills.CONCLUSION This case had significantly high expression of Ki-67 when diagnosed as PC-ALCL initially and then transitioned into sALCL,which is rare.Auto-ASCT combined with demethylation drugs effectively maintained CR and prolonged progression free survival. 展开更多

BACKGROUND The development of anaplastic lymphoma kinase(ALK)-tyrosine kinase inhibitors(TKIs)has remarkably improved the prognosis of patients with ALK-positive advanced non-small cell lung cancer(NSCLC).Alectinib,the second-generation ALK-TKI,has been approved as first-line treatment for advanced or metastatic NSCLC patients with ALK rearrangement.Neoadjuvant therapy can achieve tumor downstaging and eradicate occult lesions in patients with potentially resectable disease.Whether neoadjuvant alectinib can be a conversion therapy in ALK-positive advanced NSCLC patients remains unclear.CASE SUMMARY A 41-year-old man was pathologically diagnosed with locally advanced ALKpositive stage IIIB NSCLC.Alectinib was prescribed to induce tumor downstaging and facilitate the subsequent surgical resection.The tumor was successfully downstaged and pathological complete response was achieved.Left upper lobectomy with mediastinal lymphadenectomy was performed after tumor downstaging.The patient has continued to receive alectinib as adjuvant therapy during postoperative follow-up with a recurrence-free survival of 29 mo as of writing this report.CONCLUSION This case sheds light on the feasibility and safety of alectinib as a neoadjuvant treatment for stage IIIB NSCLC patients with ALK rearrangement.Its efficacy needs to be validated in prospective clinical trials. 展开更多

BACKGROUND Primary bone lymphoma(PBL)is an uncommon extranodal disease that represents approximately 1%-3%of lymphomas.Anaplastic lymphoma kinase(ALK)positive anaplastic large-cell lymphoma(ALCL)is an extremely rare type of PBL.The aim of this report is describe the symptoms,diagnosis,and treatment of primary bone ALK-positive ALCL.CASE SUMMARY A 66-year-old man presented to our hospital with neck and shoulder pain and intermittent fever that lasted for 1 mo.After extensive evaluation,positron emission tomography-computed tomography(CT)examination showed multiple osteolytic bone lesions without other sites lesions.CT-guided biopsy of the T10 vertebral body was performed,and the pathology results showed that neoplastic cells were positive for ALK-1,CD30,and CD3.A diagnosis of primary bone ALK positive ALCL was ultimately made.The patient was in partial response after four cycle soft cyclophosphamide,doxorubicin,vincristine,and prednisone chemotherapy,and we planned to repeat the biopsy and radiological examination after completion of the fifth cycle of therapy.CONCLUSION Primary bone ALK positive ALCL is a rare disease and physicians should keep in mind that ALCL can present with isolated osseous involvement without nodal involvement,and lymphoma should be considered in the differential diagnosis of primary bone lesions. 展开更多

BACKGROUND Rearrangements of the anaplastic lymphoma kinase(ALK)gene(ALK-positive)represent an oncogenic driver in approximately 3%-5%of non-small-lung cancer(NSCLC)patients.Sarcoidosis is a multisystem disease,and its reported incidence in Asia is 1 or less per 100000 people per year.The co-occurrence of sarcoidosis and ALK-positive NSCLC is rare,and ALK-positive lung cancer is likely to spread quickly.Therefore,the co-occurrence of sarcoidosis is more easily misdiagnosed as metastatic lung cancer by radiological examination.CASE SUMMARY A 50-year-old man had a nodule in the left superior lobe,many small nodules in left superior and right lungs,and enlarged bilateral hilar,mediastinal,and right supraclavicular lymph nodes.Computed tomography-guided pulmonary biopsy of the nodule in the left superior lobe revealed echinoderm microtubuleassociated protein-like 4 gene-ALK positive NSCLC with concomitant noncaseating granuloma.This patient was treated with crizotinib.Thirty days later,a chest computed tomography scan revealed a dramatic decrease in the size of the left superior lobe nodule;however,the lesions in the right lung progressed.The right supraclavicular lymph nodes showed granulomas,and no tumor cells were identified in the specimens. The angiotensin-converting enzyme level was high.After 1 wk of methylprednisolone treatment, a significant response of all lesionswas revealed. Following radical resection of the lung cancer, noncaseatinggranulomas were observed in both lung tissues and lymph nodes, which resultedin a diagnosis of echinoderm microtubule-associated protein-like 4-ALK positiveNSCLC accompanied with sarcoidosis.CONCLUSIONOur experience illustrates that pathological evidence is needed to confirmmetastatic disease, especially when some suspected metastatic lesions arenegative for malignancy. 展开更多

BACKGROUND Anaplastic large cell lymphoma(ALCL)is a rare and heterogeneous malignant tumor,which is classied as anaplastic lymphoma kinase(ALK)positive ALCL and ALK-ALCL.Many patients are diagnosed with ALCL at the stage of bone marrow involvement.However,ALCL patients with clinical manifestations consistent with acute leukemia are relatively rare.CASE SUMMARY In this report,the patient did not receive appropriate diagnosis and treatment despite a two-year history of lymph node enlargement.Hereafter,she was admitted for B symptoms and was diagnosed as ALK-ALCL by lymph node biopsy.Then,the disease progressed to leukemia without any treatment after 2 mo.The proportion of lymphoma cells in bone marrow was as high as 96%,and the proportion of peripheral blood was 84%.She also had clinical manifestations similar to acute leukemia.After completion of chemotherapy,she developed granulocytopenia and fever and died from septicemia.CONCLUSION ALCL with leukemic presentation is a late manifestation of lymphoma with low chemotherapy tolerance and poor prognosis. 展开更多

We report a case of a 64-year-old woman with anaplastic carcinoma of the pancreas(ACP) with cyst formation and review 60 ACP cases reported in Japan. In 20% of cases, laboratory tests revealed severe anemia(hemoglobin level < 10.0 g/d L) and elevated leucocyte counts(> 12000/mm3), which were likely attributable to rapid tumor growth, intratumoral hemorrhage, and necrosis. Elevated serum CA19-9 levels were observed in 55% of cases. Cyst-like structures were observed on imaging in 47% of cases, and this finding appears to reflect subsequent cystic degeneration in the lesion. Macroscopically, hemorrhagic necrosis was observed in 77% of cases, and cyst formation was observed in 33% of cases. ACP should be considered when diagnosing pancreatic tumors with a cyst-like appearance, especially in the presence of severe anemia, elevated leucocyte counts, or elevated serum CA19-9 levels. 展开更多

Anaplastic thyroid carcinoma(ATC)is the rarest,but deadliest histologic type among thyroid malignancies,with a dismal median survival of 3-9 mo.Even though ATC accounts for less than 2%of all thyroid tumors,it is responsible for 14%-39%of thyroid carcinoma-related deaths.ATC clinically presents as a rapidly growing mass in the neck,associated with dyspnoea,dysphagia and vocal cord paralysis.It is usually locally advanced and often metastatic at initial presentation.For operable diseases,the combination of radical surgery with adjuvant radiotherapy or chemotherapy,using agents such as doxorubicin and cisplatin,is the best treatment strategy.Cytotoxic drugs for advanced/metastatic ATC are poorly effective.On the other hand,targeted agents might represent a viable therapeutic option.Axitinib,combretastatin A4,sorafenib and imatinib have been tested in small clinical trials of ATC,with a promising disease control rate ranging from 33%to 75%.Other clinical trials of targeted therapy for thyroid carcinoma are currently ongoing.Biological agents that are under investigation include pazopanib,gefitinib and everolimus.With the very limited therapeutic armamentarium available at the present time,targeted therapy constitutes an exciting new horizon for ATC.In future,biological agents will probably represent the standard of care for this aggressive malignancy,in the same fashion as it has recently occurred for other chemo-refractory tumors,such as kidney and hepatic cancer. 展开更多

Primary anaplastic carcinoma is a rare variant of small intestinal cancer. Most reports of primary anaplastic carcinoma of the small intestine are isolated case reports, therefore the clinicopathological features, therapeutic management, and surgical outcome of this tumor type remain unclear. This review analyzes the available clinical characteristics of primary anaplastic carcinoma of the small intestine and investigates key differences from differentiated adenocarcinoma of the small intestine. A Medline search was performed using the keywords 'small intestine' and 'anaplastic carcinoma' or 'undifferentiated carcinoma'. Additional articles were obtained from references within the papers identified by the Medline search. The literature revealed a poor prognosis for patients who underwent surgical resection for anaplastic carcinoma of the small intestine, which gave a 3-year overall survival rate of 10.8% and a median survival time of 5.0 mo. The literature suggests that anaplastic carcinoma~ is markedly more aggressive than differentiated adenocarcinoma of the small intestine. Surgical resection with the aim of complete tumor removal provides the only beneficial therapeutic option for patients with anaplastic carcinoma of the small intestine, because chemotherapy and radiation therapy have no significant effect on the rate of survival. However, despite complete tumor resection, most patients with anaplastic carcinoma of the small intestine are at great risk of disease recurrence. Multicenter clinical trials are expected to provide additional therapeutic strategies and establish the efficacy of multimodality adjuvant therapy. This report also highlights the importance of a systematic diagnostic approach for anaplastic carcinoma of the small intestine. 展开更多

An 80-year-old man was admitted to our clinic for further investigation of a fever of unknown origin. He noted anorexia, weight loss and fatigue. His laboratory tests showed anemia and a great elevation of ESR, LDH, and β2 microglobulin. In CT and MRI scan, a soft tissue mass in the pancreas was observed. A repeated endoscopy after his admission revealed an ulcerated mass-like deformity of the duodenal bulb. Explorative laparotomy confirmed a diffuse spread of an unresectable malignant pancreatic mass extending to the adjacent organs. Duodenal and surgical biopsies identified an ALCL of T-cell lineage, ALK-. The patient died in the Intensive Care Unit due to hemodynamic instability.Our case is the first one indicating that primary pancreatic lymphoma should be suspected in a patient with pancreatic mass and elevated serum LDH and β2 microglobulin. 展开更多

Introduction: The rearrangement of the anaplastic lymphoma kinase(ALK) gene accounts for approximately 1%–6% of lung adenocarcinoma cases and deines a molecular subgroup of tumors characterized by clinical sensitivity to ALK inhibitors such as crizotinib. This study aimed to identify the relationship between ALK rearrangement and the clinico?pathologic characteristics of non?small cell lung cancer(NSCLC) and to analyze the therapeutic responses of crizotinib and conventional chemotherapy to ALK rearrangement in NSCLC patients.Methods: A total of 487 lung cancer patients who underwent testing for ALK rearrangement in our department were included in this study. ALK rearrangement was examined by using fluorescence in situ hybridization(FISH) assay.Results: Among the 487 patients, 44(9.0%) were diagnosed with ALK rearrangement by using FISH assay. In 123 patients with adenocarcinoma who were non?smokers and of a young age(≤58 years old), the frequency of ALK rearrangement was 20.3%(25/123). Short overall survival(OS) was associated with non?adenocarcinoma tumor type(P = 0.006), poorly diferentiated tumors(P al growth factor rece= 0.001), advanced?stage tumors(P < 0.001), smoking history(P ptor(EGFR)(P = 0.008), and wild?type epidermrter time to cancer p= 0.008). Moreover, patients with poorly diferentiated and advanced?stage tumors had a shorogression compared with those with well diferentiated(P = 0.023) and early?stage tumors(P = 0.001), respectively.Conclusions: ALK?rearranged NSCLC tends to occur in younger individuals who are either non?smokers or light smokers with adenocarcinoma. Patients with ALK rearrangement might beneit from ALK inhibitor therapy. 展开更多

We herein report a case of anaplastic carcinoma of the pancreas with remarkable intraductal tumor growth into the main pancreatic duct.A 76-year-old male was referred to our hospital for treatment of a pancreatic tumor.Preoperative examinations revealed a poorly defined tumor in the main pancreatic duct in the body of the pancreas,accompanied with severe dilatation of the main pancreatic duct,which was diagnosed as an intraductal papillary-mucinous neoplasm.We performed distal pancreatectomy and splenectomy.The pathological examination revealed that the tumor consisted of a mixture of anaplastic carcinoma(giant cell type)and adenocarcinoma in the pancreas.There was a papillary projecting tumor composed of anaplastic carcinoma in the dilated main pancreatic duct.The patient is now receiving chemotherapy because liver metastasis was detected 12 mo after surgery.In this case,we could observe a remarkable intraductal tumor growth into the main pancreatic duct.We also discuss the pathogenesis and characteristics of this rare tumor with specific tumor growth. 展开更多

BACKGROUND Anaplastic thyroid carcinoma(ATC),also called undifferentiated thyroid cancer,is the least common but most aggressive and deadly thyroid gland malignancy of all thyroid cancers[1].It has poor prognosis,and is the leading cause of death from malignant thyroid tumors.The one-year survival rate is 20%,with a median overall survival(OS)of only 5 mo[2].The aim of this report is to provide our experience in the diagnosis and treatment of ATC.CASE SUMMARY A patient with a thyroid mass underwent surgical treatment after developing symptoms of hoarseness.The resected tumor was pathologically diagnosed as ATC.Imaging examination revealed organ and lymph node metastasis.After multiple cycles of chemotherapy and local radiotherapy,the metastases were not relieved and gradually increased in size and new metastases appeared.The patient immediately received immunotherapy combined with targeted therapy.During treatment,immune-related adverse reactions occurred,which were improved after symptomatic treatment,and tolerated by the patient.The OS of the patient was more than 30 mo after immunotherapy combined with targeted therapy.CONCLUSION For metastatic ATC,surgical treatment,radiotherapy and chemotherapy have no significant effect on remission of the disease.However,immunotherapy has made a breakthrough in the treatment of ATC。 展开更多
