DT 9404 AU Simpson JK; Mills W; Spittle MF; Meyerstein Institute of Clinical Oncology, Middlesex Hospital,; London, UK. SO Clin Oncol (R Coll Radiol). 1993;5(6):375-7. Unique Identifier : AIDSLINE MED/94137637 AB High grade non-Hodgkin's lymphoma accounts for only 5%-10% of all non-Hodgkin's lymphoma. Infection with the human immunodeficiency virus increases the risk of developing high grade, usually B-cell, lymphoma, which has been noted to occur more commonly in homosexual men. These lymphomas often have unusual clinical presentations. We report five cases of high grade non-Hodgkin's lymphoma in HIV negative homosexual men who presented to our hospital in a 13-month period. As a major centre for the treatment of the acquired immune deficiency syndrome, there may be a self-selected homosexual population attending for medical care, and thus a bias in the relative incidence of lymphoma seen in this group.
