Discharge of the fetal bones or even the whole of an extrauterine fetus by the rectum is not uncommon. There are two early cases mentioned in which the bones of a fetus were discharged at stool, causing intense pain. Armstrong describes an anomalous case of pregnancy in a syphilitic patient who discharged fetal bones by the rectum. Bubendorf reports the spontaneous elimination of a fetal skeleton by the rectum after five years of retention, with recovery of the patient. Butcher speaks of delivery through the rectum at the fourth month, with recovery. Depaul mentions a similar expulsion after a pregnancy of about two months and a half. Jackson reports the dissection of an extrauterine sac which communicated freely with the large intestine. Peck has an example of spontaneous delivery of an extrauterine fetus by the rectum, with recovery of the mother. Skippon, in the early part of the last century, reports the discharge of the bones of a fetus through an "imposthume" in the groin. Other cases of anal discharge of the product of extrauterine conception are recorded by Winthrop, Woodbury, Tuttle, Atkinson, Browne, Weinlechner, Gibson, Littre, Magruder, Gilland, and many others. De Brun du Bois-Noir speaks of the expulsion of extrauterine remains by the anus after seven years, and Heyerdahl after thirteen years. Benham mentions the discharge of a fetus by the rectum; there was a stricture of the rectum associated with syphilitic patches, necessitating the performance of colotomy. Bartholinus and Rosseus speak of fetal bones being discharged from the urinary passages. Ebersbach, in the Ephemerides of 1717, describes a necropsy in which a human fetus was found contained in the bladder. In 1878 White reported an instance of the discharge of fetal remains through the bladder.
