Three Cases of Adult T Cell Leukemia with Bone Lesion

Adult T-Cell Leukemia/Lymphoma with Gastric Lesion

Adult T-cell leukemia/lymphoma with gastric lesions. Report of three cases.

We describe three cases of adult T-cell leukemia/lymphoma (ATL) with malignant cell infiltration into the stomach. Case 1, a 63-year-old man, had a large ulcerative lesion on the lesser curvature of the upper stomach. Case 2, a 44-year-old man, had an irregular depressed lesion simulating a IIc-type early gastric cancer on the posterior wall of the mid portion of the stomach. Case 3, a 58-year-...

Specific cutaneous manifestations in adult T cell leukemia/lymphoma

Background and aim: Adult T cell leukemia/lymphoma (ATLL) is an aggresive malignancy which may occur in human T lymphotropic virus1(HTLV1) infected persons. 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...

Altered 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...

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...
