Gluteal manifestation of advanced Hodgkin's disease

Hodgkin's disease (HD) is a nodal malignancy with a characteristically axial pattern of spread and with contiguous progression via lymphatic channels. Even when dissemination occurs beyond the lymphoreticular system, certain patterns of associated spread are frequently evident. We describe a case of nodular sclerosis HD with a 12-year indolent course and late involvement of the gluteal muscle. Initially, stage was IVb with spleen and bone marrow involvement, complicated by a Coomb's positive hemolytic anemia. Following chemotherapy, the patient had a partial response with the subsequent long course of slowly progressive disease invading first the urinary bladder and, later, the gluteus. Involvement of the gluteal muscle is a rare event in HD. Spread to the gluteus occurred most likely by contiguity, via retroperitoneal lymph nodes.
