[Ergotamine-induced anal ulcer].

Chronic, extensive anal ulceration following haemorrhoidectomy and excessive application of ergot suppositories was observed in a 61 year old patient, suffering for years. The diagnosis of an anocutaneous ergotism was not arrived at before 10 months, treatment in several hospitals and two operations including a sigmoid colostomy. Complete healing within several weeks ensued from discontinuation of the suppositories. Symptoms, histological features, pathogenesis and therapy are discussed. Two further cases could be observed meanwhile.
