title: [Splenic lymphoma of Ki-1 positive B-cell type treated with CHOP].
abstract: A 75-year old man was admitted to our hospital by complaining of his left supraclavicular lymphadenopathy. Physical examination also revealed splenomegaly and cervical lymphadenopathy. An abdominal CT scan showed paraaortic lymphadenopathy and splenomegaly with multiple low density area. A pathological diagnosis of Ki-1 lymphoma was made by the biopsied supraclavicular lymph node because the node consists of large cells with clear cytoplasms and conspicuous nucleoli and large cells were positive for IgM, lambda, CD20 and CD30 (Ki-1). The primary lesion of lymphoma was suspected to be spleen because of the radiological finding of the spleen. The patient responded to systemic chemotherapy (CHOP) with complete remission. Pathological and clinical characteristics of this B-cell Ki-1 lymphoma were discussed.
