Simultaneous presentation of relapsing Hodgkin's disease and treatment-related non-Hodgkin's lymphoma.

A 55-year-old white man was diagnosed in 1975 with Hodgkin's disease stage IIA, mixed cellularity. He was treated with 4,500 rads to an inverted-Y field followed by six cycles of MOPP and remained in complete remission. In 1983 a right axillary lymph node biopsy showed recurrent Hodgkin's disease, mixed cellularity. While receiving his initial chemotherapy he developed persistent epigastric distress. Endoscopic gastric biopsy demonstrated a diffuse large-cell non-Hodgkin's lymphoma. Surface marker studies confirmed the separate identity of these two malignant lymphoproliferative processes. This represents the first reported simultaneous occurrence of relapsing Hodgkin's disease with treatment-related non-Hodgkin's lymphoma.
