Ward reports the successful removal of a dermoid cyst weighing 30 pounds from a woman of thirty-two, the mother of two children aged ten and twelve, respectively. The report is briefly as follows: "The patient has always been in good health until within the last year, during which time she has lost flesh and strength quite rapidly, and when brought to my hospital by her physician, Dr. James of Williamsburg, Kansas, was quite weak, although able to walk about the house. A tumor had been growing for a number of years, but its growth was so gradual that the patient had not considered her condition critical until quite recently. The tumor was diagnosed to be cystoma of the left ovary. Upon opening the sac with the trocar we were confronted by complications entirely unlooked for, and its use had to be abandoned entirely because the thick contents of the cyst would not flow freely, and the presence of sebaceous matter blocked the instrument. As much of the fluid as possible was removed, and the abdominal incision was enlarged to allow of the removal of the large tumor. An ovarian hematoma the size of a large orange was removed from the right side. We washed the intestines quite as one would wash linen, since some of the contents of the cyst had escaped into the abdominal cavity. The abdomen was closed without drainage, and the patient placed in bed without experiencing the least shock. Her recovery was rapid and uneventful. She returned to her home in four weeks after the operation. "The unusual feature in this case was the nature of the contents of the sac. There was a large quantity of long straight hair growing from the cyst wall and an equal amount of loose hair in short pieces floating through the tumor-contents, a portion of which formed nuclei for what were called 'moth-balls,' of which there were about 1 1/2 gallons. These balls, or marbles, varied from the size of moth-balls, as manufactured and sold by druggists, to that of small walnuts. They seemed to be composed of sebaceous matter, and were evidently formed around the short hairs by the motion of the fluid produced by walking or riding. There was some tissue resembling true skin attached to the inner wall of the sac." There are several cases of multiple dermoid cysts on record, and they may occur all over the body. Jamieson reports a case in which there were 250, and in Maclaren's case there were 132. According to Crocker, Hebra and Rayer also each had a case. In a case of Sangster, reported by Politzer, although most of the dermoids, as usual, were like fibroma-nodules and therefore the color of normal skin, those over the mastoid processes and clavicle were lemon-yellow, and were generally thought to be xanthoma until they were excised, and Politzer found they were typical dermoid cysts with the usual contents of degenerated epithelium and hair.
