Perianal disease of tuberculous origin: report of a case and review of the literature.

Abstract

A case of anal tuberculosis in an otherwise asymptomatic patient with bleeding anal ulcers is presented. The clinical features of this entity and the problems in differential diagnosis between anal infectious vs. inflammatory diseases are discussed. The management and outcome of the case of an adult patient who presented with perianal ulcers is described. On a three-drug antituberculous regimen, symptoms abated, radiographic infiltrates improved, and perianal ulcers healed. Anal tuberculosis is an extremely rare disease. A tuberculous origin must be considered when the cause of perianal ulcers is unclear to avoid undesirable delays in the diagnosis and treatment of this disease.
