Unusual Presentation of Digestive Tuberculosis: About A Case Report

Tuberculosis is a public health issue. Pulmonary form is the most common, and isolated ano-perineal involvement is very rare. We describe in this paper a case of an ano-perineal tuberculosis in a 26-year-old, who was admitted for a recurrent fistula and chronic perianal ulcerations. Many investigations were made, including Human Immunodeficiency Virus (HIV) and syphilis serologies, ileocolonoscopy, chest X-ray, and they all revealed no abnormalities. The Tuberculin intradermal reaction was positive with a 15 mm induration. Histopathological examination of perianal ulceration’s biopsies revealed epithelioid cell granuloma accompanied by Langhans multinucleated giant cells and enclosing caseating necrosis, which allowed us to diagnose an anoperineal tuberculosis. The patient was successfully treated by a 6-month regimen.
