title: Tuberculous anal ulcer.
abstract: Two patients with anorectal tuberculosis, without prior or concurrent knowledge of active pulmonary infection with mycobacteria, are described. Anal fissure in an unusual location which is slow to heal should have a biopsy performed, with appropriate stains and cultures carried out, to rule out tuberculous disease. Chemotherapy is then highly effective for ulcerative perianal tuberculosis.
