Coexistence of Kaposi's sarcoma and chronic lymphocytic leukemia in the same lymph node.

A patient with chronic lymphocytic leukemia in whom a carcinoma of the gall bladder was previously found is described. The patient was treated with prednisone and chlorambucil and developed a significant lymphadenopathy. A biopsy of one of the lymph nodes revealed the coexistence of Kaposi's sarcoma and chronic lymphocytic leukemia in the same node. This and the presence of three malignancies in the same patient are discussed.
