INTRODUCTION Anaplastic large cell lymphoma is a rare type of non-Hodgkin lymphoma. The most common extranodal sites of anaplastic large cell lymphoma are skin, subcutaneous tissue, bone, lung, and gastrointestinal organs. The involvement of the skeletal muscle has been described rarely in extranodal anaplastic large cell lymphoma. CASE PRESENTATION An 89-year-old Japanese man visited our hos...

Hypersensitivity to mosquito bites is defined as the appearance of intense skin reactive lesions and systemic symptoms subsequent to mosquito bites. Most cases of hypersensitivity to mosquito bites reported thus far have been associated with chronic Epstein-Barr virus infection or natural killer cell leukemia/lymphoma. In this study, we describe the case of an 18-year-old Korean boy who had hyp...

Anaplastic large cell lymphoma (ALCL) is the second most common type of peripheral T and an aggressive mature lymphoma. About 50 to 70% systemic ALCLs are anaplastic kinase positive (ALK +), proportion even higher in pediatric population. The 5-year survival after chemotherapy around 70 80%. But there a subgroup ALK+ ALCL patients who refractory chemotherapy. Brentuximab vedotin approved agent ...

radioiodine (1-131) is the treatment of choice in differentiated thyroid carcinoma. external radiotlierapy however, has it's own roie in these tumors. treatment of anaplastic thyroid carcinoma 1ms not acliieved any notahle success yet, though combined - modality regimens of radiotherapy and chemotherapy have sometimes shown significant results. in this paper the role of radiotlierapy and chemot...

ALCL: anaplastic large cell lymphoma CL: composite lymphoma EBV: Epstein-Barr virus MF: mycosis fungoides INTRODUCTION Patients with mycosis fungoides (MF) are at increased risk of a second malignant neoplasm, especially lymphoma. We report a sexagenarian with a 14-year history of patch MF, stage IB, who had intravascular cutaneous anaplastic large cell lymphoma (ALCL) and cutaneous composite l...

BACKGROUND The role of β-catenin in cancer has been most studied in tumors of epithelial cell origin. The functional status and biological significance of this protein in anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma is unknown. DESIGN AND METHODS ALK-positive anaplastic large cell lymphoma cell lines and patients' tumor samples were examined for status of β-catenin...

Introduction: Anaplastic large-cell lymphoma occurring in the nasal cavity is a rare disease. The latest World Health Organization (WHO) Classification recognizes three distinct subtypes: primary systemic anaplastic lymphoma kinase positive been our case, primary systemic anaplastic lymphoma kinase negative and primary cutaneous types. Through this case study, we focus on the clinical presentat...

The prognosis of the primary refractory anaplastic lymphoma kinase (ALK+) anaplastic T large cell lymphoma is ominous. The identification of molecular targets with potential to drive oncogenesis remains a cornerstone for the designing of new selective cancer therapies. Crizotinib is a selective ATP-competitive inhibitor for ALK, approved for its use in lung cancer with rearrangements on ALK gen...

Primary cutaneous anaplastic large T-cell lymphoma CD30+ is a rare lymphoma, which belongs to the group of lymphoproliferations CD30+. It characterized by an excellent prognosis and treatment therefore not very aggressive. However, its histological molecular characteristics have many similarities with lymphoproliferative diseases whose completely different. For this reason, it important study p...

Anaplastic large cell lymphomas are peripheral T-cell lymphomas that are characterized by a proliferation of large anaplastic blasts expressing CD30. In children, systemic anaplastic large cell lymphomas often present at advanced clinical stage and harbor translocations involving the anaplastic lymphoma kinase (ALK) gene leading to the expression of chimeric anaplastic lymphoma kinase (ALK)-fus...
