LYMPHOMA CUTIS OF APPARENT B-CELL ORIGIN

Abstract

A nodular, poorly differentiated lymphocytic lymphoma involving lymph nodes, spleen and skin is reported in a 60 yr old man. The clinical course of this disorder strongly implied cutaneous involvement as the initial site of disease. Immunologic studies indicated that the neoplastic cells carried surface immunoglobulin (IgM.lambda.), thus suggesting a B [bone marrow-derived] lymphocyte origin for the lymphatic neoplasia.
