Gangrenous ischemic colitis of the rectum: a rare complication of systemic lupus erythematosus.

Abstract

Ischemic colitis with colonic necrosis is one of the uncommon gastrointestinal complications of systemic lupus erythematosus. In the few reported cases, only the abdominal part of the colon was involved with rectal sparing. This is the first report of gangrenous ischemic colitis isolated to the rectum, due to systemic lupus erythematosus vasculitis.
