Weil reported the case of a man of twenty-two years who was born with what was supposed to be a spina bifida in the lower sacral region. According to Senn, the swelling never caused any pain or inconvenience until it inflamed, when it opened spontaneously and suppurated, discharging a large quantity of offensive pus, hair, and sebaceous material, thus proving it to have been a dermoid. The cyst was freely incised, and there were found numerous openings of sweat glands, from which drops of perspiration escaped when the patient was sweating. Dermoid cysts of the thorax are rare. Bramann reported a case in which a dermoid cyst of small size was situated over the sternum at the junction of the manubrium with the gladiolus, and a similar cyst in the neck near the left cornu of the hyoid bone. Chitten removed a dermoid from the sternum of a female of thirty-nine, the cyst containing 11 ounces of atheromatous material. In the Museum of St. Bartholomew's Hospital in London there is a congenital tumor which was removed from the anterior mediastinum of a woman of twenty one, and contained portions of skin, fat, sebaceous material, and two pieces of bone similar to the superior maxilla, and in which several teeth were found. Dermoids are found in the palate and pharynx, and open dermoids of the conjunctiva are classified by Sutton with the moles. According to Senn, Barker collected sixteen dermoid tumors of the tongue. Bryk successfully removed a tumor of this nature the size of a fist. Wellington Gray removed an enormous lingual dermoid from the mouth of a negro. It contained 40 ounces of atheromatous material. Dermoids of the rectum are reported. Duyse reports the history of a case of labor during which a rectal dermoid was expelled. The dermoid contained a cerebral vesicle, a rudimentary eye, a canine and a molar tooth, and a piece of bone. There is little doubt that many cases of fetus in fetu reported were really dermoids of the scrotum.
