Alimentary tract biopsy lesions in the acquired immune deficiency syndrome

The surgical pathology of the alimentary tract complications of the acquired immune deficiency syndrome (AIDS) is described and illustrated by a review of one year's material accessioned at a New York Community Hospital. Cytomegalovirus, Cryptosporidium and Mycobacterium avium-intracellulare were particularly notable among diverse opportunistic infectious agents. Visceral Kaposi's sarcoma and malignant lymphomas were the principal malignancies recognized, and their occurrence in young men should alert clinicians to the possibility of AIDS.
