title: Virus-associated colitis in homosexual men: two case reports.
abstract: Two homosexual men with colitis are described. In each case there was evidence of viral infection of the colon. One patient developed toxic megacolon that responded to conservative therapy. The other patient had proctosigmoiditis and opportunistic infections that eventually led to his death. An intensive search for viruses should be made in all homosexual men with proctitis and/or colitis.
