Perianal tuberculosis is an uncommon variant of extra pulmonary tuberculosis and mimics other common perianal conditions. We report two patients with perianal tuberculosis. An 82-year-old male presenting with purulent perianal discharge and weight loss. A pelvic magnetic resonance imaging showed a low trans sphincteric anorectal fistula with abscess formation. A fistulectomy was performed and the pathological study showed a granulomatous-tuberculous chronic inflammation. Mycobacteria were recovered from gastric contents. A 48-year-old male with the same symptoms. An ulcerated lesion in the anal region was biopsied, disclosing a granulomatous inflammatory process with Ziehl-Nielsen stainable organisms.
