Abstract

A 61 year old man with long standing common variable immunodeficiency presented with pyrexia, anaemia and leucopenia. A diagnoses of Hodgkin's disease of the bone marrow was made. The typical histopathological and immunophenotypic appearances were clearly distinct from those of T cell lymphoma with Reed-Sternberg-like cells which, in contrast to Hodgkin's disease, is a known complication of common variable immunodeficiency. Complete clinical and histological remission was achieved with combination chemotherapy. The latter was complicated by severe myelosuppression, unusually severe erosive mucositis and viral retinitis.
