Anorectal ergotism: another cause of solitary rectal ulcers

Abstract

Anorectal ulceration was observed in 6 patients who excessively used suppositories containing ergotamine tartrate. The mucosal lesions of the rectum resembled those observed in the "solitary rectal ulcer syndrome." However, characteristic features of ergotamine-induced ulcers are absence of a mucosal prolapse, lack of a history of constipation, and rapid healing after discontinuation of the drug. Furthermore, the rectal lesion may be associated with anal ulceration, which occasionally presents as the only clinical manifestation of "anorectal ergotism."
