They may be quite superficial, follicular, orsufficiently deep to perforate the bowel and cause peritonitisor ischio-rectal abscess and fistula. On account of the functionof the rectum and the nature of the disease, tubercular ulcera-tion rarely heals. When healing does occur, there may besufficient contraction to produce partial or complete rare cases of tuberculous ulceration at the anal margin inwhich the disease progresses rapidly and the parts are not kept.
