title: Lymphogranuloma venereum of the rectum in a homosexual man. Case report.
abstract: A male homosexual presented initially with bloody diarrhoea and a swelling in the left groin, which was unsuccessfully treated with erythromycin. Examination in hospital showed a rectal mass and an abscess in the left groin. Histological examination of the rectal mass and a positive lymphogranuloma complement fixation test result confirmed the diagnosis of lymphogranuloma venereum. This disease, although rare, should not be forgotten in the differential diagnosis of rectal problems in male homosexuals.
