The clinicopathologic features of a Korean patient with adult T-cell leukemia/lymphoma(ATLL) are presented. A 51-year-old man, who has lived in Korea since birth, had multiple cutaneous nodules and multiple lymphadenopathy for the previous two months. A histopathologic study of the lymph node and skin lesion revealed T-cell non-Hodgkin's lymphoma of pleomorphic type, medium and large cell type. Peripheral blood examination showed leukemic features with 30% of abnormal lymphoid cells. HTLV-I proviral DNA pX region was detected in the DNA from peripheral blood mononuclear cells(PBMC) and the specific gag, pol, and env HTLV-I sequences were detected in the lymph node using polymerase chain reaction technique. Human T-cell leukemia/lymphoma type I(HTLV-I) antibodies were present in the serum. An immunophenotypic study of the lymph node revealed CD4 positive and CD8 negative helper/inducer T cell type surface markers. This case is the acute type, i.e. prototypic ATLL. He was treated with an intensive chemotherapy including cyclophosphamide, etoposide, doxorubicin, vincristine, and prednisone. Despite initial transient improvement, the tumor progressed after three cycles of the regimen and became refractory to further chemotherapy. These clinicopathologic findings, including the immunophenotypic analysis, established with certainty the diagnosis of HTLV-I-induced adult T-cell leukemia/lymphoma.

A 60-year-old woman from the town of Mashhad in northeastern Iran developed cardiac failure due to aortic and mitral regurgitations which needed cardiac valve replacement. Histopathological study of the valves revealed a T-cell non-Hodgkin's lymphoma. Blood examination showed leukemic features with 32% of abnormal white blood cells. Human T-cell leukemia/lymphoma virus type I (HTLV-I) antibodies were present in the serum and the specific env HTLV-I sequences were detected in the DNA extracted from the valves and peripheral blood mononuclear cells (PBMC) using polymerase chain reaction technique. Clonal integration of two HTLV-I copies was found in both the valves and PBMC DNA, thus the diagnosis of adult T-cell leukemia/lymphoma (ATL) was established. In contrast to the acute life-threatening cardiac localization, our case met the diagnostic criteria of chronic ATL, this was confirmed by favorable evolution without chemotherapy during the 24 months after diagnosis. According to our knowledge, this is the first report of an isolated lymphomatous cardiac valve involvement, without other cardiac abnormalities. It seems important to underline that the patient originated from Iran where endemicity of HTLV-I has only recently been discovered.
