BACKGROUND Both thyroid lymphoma and anaplastic carcinoma of thyroid present with rapidly growing mass in eldery patients. Anaplastic carcinoma has high mortality rate and combination of surgery, radiation therapy and multidrug chemotherapy are the best chance for cure. Prognosis of thyroid lymphoma is excellent and chemotherapy for widespred lymphoms and radiotherapy with or without adjuvant c...

Anaplastic large cell lymphoma (ALCL) is a histological subtype of non-Hodgkin lymphoma, largely characterized by anaplastic kinase (ALK) positivity, resulting from the chromosomal translocation t(2;5). We report pediatric case ALK-positive ALCL with primary concomitant involvement bone and central nervous system (CNS); thereafter, literature review about CNS was conducted. According to analyze...

Anaplastic large cell lymphoma is a rare disease associated with breast implants. We present the case of a woman who had had breast augmentation and multiple revisions over a period of 13 years and presented with recurrent fluid collections. The cause was determined to be anaplastic large cell lymphoma, which required removal of the implants, capsulectomy, and evaluation by a medical oncologist...

INTRODUCTION Anaplastic large cell lymphoma is a subset of non-Hodgkin lymphoma and an unusual disease in children. CASE PRESENTATION Herein we have reported a 7- year- old girl with a large necrotic skin ulcer on the chest caused by systemic form of anaplastic large-cell lymphoma and simultaneous active toxoplasmosis diagnosed by PCR on lymph node specimen. There were few reports showing a r...

The anaplastic large cell lymphoma is a rare entity in pediatric patients. We present an unusual case of pericardial involvement, quite uncommon as extranodal presentation of this type of disorder, that provoked a life-risk situation requiring an urgent pericardiocentesis. To our knowledge, this is the first report on a child with pericardial involvement without an associated cardiac mass secon...

A characteristic feature of anaplastic large cell lymphoma is the significant repression of the T-cell expression program despite its T-cell origin. The reasons for this down-regulation of T-cell phenotype are still unknown. To elucidate whether epigenetic mechanisms are responsible for the loss of the T-cell phenotype, we treated anaplastic large cell lymphoma and T-cell lymphoma/leukemia cell...

BACKGROUND T-cell lymphomas with anaplastic morphology typically comprise of anaplastic lymphoma kinase positive, anaplastic large cell lymphoma (ALK+ ALCL), ALK-negative ALCL (ALK- ALCL), and primary cutaneous ALCL (PC-ALCL). However, other entities such as diffuse large B-cell lymphoma, peripheral T-cell lymphoma, Hodgkin lymphoma, and undifferentiated carcinoma can also show similar anaplast...

The NPM-ALK fusion protein is found in ALK(+) anaplastic large cell lymphomas harboring the t(2;5) chromosomal translocation. Patients harboring ALK translocations typically have an excellent prognosis with conventional chemotherapy and a reported 5-year survival rate of 70%. Although most patients with ALK(+) anaplastic large cell lymphoma have a good prognosis, some patients do not respond to...

BACKGROUND In vitro studies confirmed cytoreductive anti-tumor activity of crizotinib in experimental models of anaplastic large cell lymphoma in 2007. One case series and a few case reports describe the use of crizotinib in relapsed or refractory anaplastic lymphoma kinase-positive anaplastic large cell lymphoma. Even though data are limited regarding the dose of crizotinib in renal insufficie...
