Gangrenous perforating uteritis.

A massive intrauterine fecal impaction with gangrene and uterine rupture occurred in an 80-year-old woman from a ruptured diverticulitis of the colon which penetrated into the fundus of the uterus. Cicatricial stenosis of the cervix and distensibility of the fundus together with stool discharging into the uterus caused a sequence of events similar to that of appendicitis. The patient recovered after hysterectomy, peritoneal flap closure of the low pelvic colon fistula site, and sigmoid colostomy.
