A 56-year-old man presented with an inguinal lymph node enlargement. Histologic study of the tumor revealed three intermingled pathologic lesions: a nodular small cell lymphoma, an angiofollicular hyperplasia of vasculohyaline type, and a vascular neoplasia closely resembling Kaposi's sarcoma. The patient was immunocompetent and denied any homosexual relationships, transfusions, or drug use. The serum was negative for the presence of human immunodeficiency virus antibody. Computed tomographic scan and ultrasound examination revealed no other lymphadenopathies. This case shows that both hyperplastic and neoplastic lymphoid proliferations can occur simultaneously with vascular neoplasia. It thereby suggests that the neoplastic populations might interact to favor the tumor growth, the sequence and the nature of the stimulating events remaining unclear.
