Six Cases of CD20-Positive Adult T-Cell Leukemia.
Adult T-cell leukaemia/lymphoma (ATLL) is a neoplasm originating in mature CD4+ peripheral T cells. However, rare cases of CD20+ ATLL have been reported. Here, we describe six cases of CD20+ ATLL diagnosed in our department. The median age was 79 years (range, 54-90 years); two patients were men, and four were women. Elevated lactate dehydrogenase was observed in four cases. All cases were lymp...
متن کاملSpecific cutaneous manifestations in adult T cell leukemia/lymphoma

HTLV1 is endemic in Khorasan with prevalence of 2.3% in general population. Since specific cutaneous manifestations of lymphoma may occur in a significant number of patients, we studied ATLL patients in Mashhad.Mate...
متن کاملAltered expression of cell cycle regulators in adult T-cell leukemia/lymphoma patients
Abstract Background: Adult T-cell leukemia/lymphoma (ATLL) is caused by human T-cell lymphotropic virus type-1 (HTLV-1). HTLV-1 oncogenes can induce malignancy through controlled gene expression of cell cycle checkpoints in the host cell. HTLV-I genes play a pivotal role in overriding cell cycle checkpoints and deregulate cellular division. In this study, we aimed to determine and comp...
متن کاملCD20 positive T-cell lymphoma/leukemia: a rare entity with potential diagnostic pitfalls.
Mature T-cell neoplasms are relatively uncommon, accounting for approximately 10% of all non-Hodgkin lymphomas. This category of hematopoietic neoplasms is clinically aggressive and shows a poor response to therapy and shortened survival. The antigen CD20 has long been thought to be a specific marker for B-cell lineage and has been used to help differentiate T-cell and B-cell neoplasms. We pres...
متن کاملAdult T-cell leukemia/lymphoma.
Adult T-cell leukemia/lymphoma (ATL) is a malignancy of mature CD4+ T-cells caused by human T-cell lymphotropic virus type 1 (HTLV-1). Twenty million people are believed to be infected throughout the world, mostly in Japan, Africa, the Caribbean, and South America, particularly in Brazil and Peru. ATL affects about 5% of infected individuals and is classified in the following clinical forms: ac...
