Abstract: This work reports a case of a 49-year-old male suffering from chronic tuberculosis who developed painful ulcers around the anus for approximately eight months. The colonoscopy revealed the presence of ulcers in the transverse colon, which were also found in the skin and intestine, as revealed by microscopic examination. The skin ulcer was positive for tuberculosis bacilli, leading to the final diagnosis of Tuberculosis cutis orificialis. The patient had a previous history of tuberculosis, which indicated that the infection in the lungs moved down to invade the intestines and finally the skin.
