Rectal Tuberculosis Mimicking Rectal Cancer

Abstract

In recent years, tuberculosis has had a significant rise, caused mainly by the epidemic of acquired immunodeficiency syndrome. The anorectal tuberculosis is a very rare presentation. Herein, we presented a 67-year-old man who has had renal transplantation and presented with hematochezia and painful defecation since 6 months before. Biopsy was taken from the lower rectal ulcerated lesion. Histopathology revealed granulomatous lesion in the submucosa and presence of acid fast bacilli in Ziel-Nelson staining. The involvement of rectal wall without any other primary sites of tuberculosis showed the primary nature of rectal tuberculosis.
