Brodie speaks of a case in which fetal remains were taken from the abdomen of a girl of two and one-half years. Gaither describes a child of two years and nine months, supposed to be affected with ascites, who died three hours after the physician's arrival. In its abdomen was found a fetus weighing almost two pounds and connected to the child by a cord resembling an umbilical cord. This child was healthy for about nine months, and had a precocious longing for ardent spirits, and drank freely an hour before its death.
Blundell says that he knew "a boy who was literally and without evasion with child, for the fetus was contained in a sac communicating with the abdomen and was connected to the side of the cyst by a short umbilical cord; nor did the fetus make its appearance until the boy was eight or ten years old, when after much enlargement of pregnancy and subsequent flooding the boy died." The fetus, removed after death, on the whole not very imperfectly formed, was of the size of about six or seven months' gestation. Bury cites an account of a child that had a second imperfectly developed fetus in its face and scalp. There was a boy by the name of Bissieu who from the earliest age had a pain in one of his left ribs; this rib was larger than the rest and seemed to have a tumor under it. He died of phthisis at fourteen, and after death there was found in a pocket lying against the transverse colon and communicating with it all the evidences of a fetus.
At the Hopital de la Charite in Paris, Velpeau startled an audience of 500 students and many physicians by saying that he expected to find a rudimentary fetus in a scrotal tumor placed in his hands for operation. His diagnosis proved correct, and brought him resounding praise, and all wondered as to his reasons for expecting a fetal tumor. It appears that he had read with care a report by Fatti of an operation on the scrotum of a child which had increased in size as the child grew, and was found to contain the ribs, the vertebral column, the lower extremities as far as the knees, and the two orbits of a fetus; and also an account of a similar operation performed by Wendt of Breslau on a Silesian boy of seven. The left testicle in this case was so swollen that it hung almost to the knee, and the fetal remains removed weighed seven ounces.
Sulikowski relates an instance of congenital fetation in the umbilicus of a girl of fourteen, who recovered after the removal of the anomaly. Aretaeos described to the members of the medical fraternity in Athens the case of a woman of twenty-two, who bore two children after a seven months' pregnancy. One was very rudimentary and only 21 inches long, and the other had an enormous head resembling a case of hydrocephalus. On opening the head of the second fetus, another, three inches long, was found in the medulla oblongata, and in the cranial cavity with it were two additional fetuses, neither of which was perfectly formed.
Broca speaks of a fetal cyst being passed in the urine of a man of sixty-one; the cyst contained remnants of hair, bone, and cartilage. Atlee submits quite a remarkable case of congenital ventral gestation, the subject being a girl of six, who recovered after the discharge of the fetal mass from the abdomen. McIntyre speaks of a child of eleven, playing about and feeling well, but whose abdomen progressively increased in size 1½ inches each day. After ten days there was a large fluctuating mass on the right side; the abdomen was opened and the mass enucleated; it was found to contain a fetal mass weighing nearly five pounds, and in addition ten pounds of fluid were removed. The child made an early recovery. Rogers mentions a fetus that was found in a man's bladder. Bouchacourt reports the successful extirpation of the remains of a fetus from the rectum of a child of six. Miner describes a successful excision of a congenital gestation.
Modern literature is full of examples, and nearly every one of the foregoing instances could be paralleled from other sources. Rodriguez is quoted as reporting that in July, 1891, several newspapers in the city of Mexico published, under the head of "A Man-mother," a wonderful story, accompanied by wood-cuts, of a young man from whose body a great surgeon had extracted a "perfectly developed fetus." One of these wood-cuts represented a tumor at the back of a man opened and containing a crying baby. In commenting upon this, after reviewing several similar cases of endocymian monsters that came under his observation in Mexico, Rodriguez tells what the case which had been so grossly exaggerated by the lay journals really was: An Indian boy, aged twenty-two, presented a tumor in the sacrococcygeal region measuring 53 cm. in circumference at the base, having a vertical diameter of 17 cm. and a transverse diameter of 13 cm. It had no pedicle and was fixed, showing unequal consistency. At birth this tumor was about the size of a pigeon's egg. A diagnosis of dermoid cyst was made and two operations were performed on the boy, death following the second. The skeleton showed interesting conditions; the rectum and pelvic organs were natural, and the contents of the cyst verified the diagnosis.
Quite similar to the cases of fetus in fetu are the instances of dermoid cysts. For many years they have been a mystery to physiologists, and their origin now is little more than hypothetic. At one time the fact of finding such a formation in the ovary of an unmarried woman was presumptive evidence that she was unchaste; but this idea was dissipated as soon as examples were reported in children, and to-day we have a well-defined difference between congenital and extrauterine pregnancy. Dermoid cysts of the ovary may consist only of a wall of connective tissue lined with epidermis and containing distinctly epidermic scales which, however, may be rolled up in firm masses of a more or less soapy consistency; this variety is called by Orth epidermoid cyst; or, according to Warren, a form of cyst made up of skin containing small and ill-defined papillae, but rich in hair follicles and sebaceous glands. Even the erector pili muscle and the sudoriparous gland are often found. The hair is partly free and rolled up into thick balls or is still attached to the walls. A large mass of sebaceous material is also found in these cysts. Thomson reports a case of dermoid cyst of the bladder containing hair, which cyst he removed. It was a pedunculated growth, and it was undoubtedly vesical and not expelled from some ovarian source through the urinary passage, as sometimes occurs.
The simpler forms of the ordinary dermoid cysts contain bone and teeth. The complicated teratoma of this class may contain, in addition to the previously mentioned structures, cartilage and glands, mucous and serous membrane, muscle, nerves, and cerebral substance, portions of eyes, fingers with nails, mammae, etc. Figure 64 represents a cyst containing long red hair that was removed from a blonde woman aged forty-four years who had given birth to six children. Cullingworth reports the history of a woman in whom both ovaries were apparently involved by dermoids, who had given birth to 12 children and had three miscarriages—the last, three months before the removal of the growths. The accompanying illustration, taken from Baldy, pictures a dermoid cyst of the complicated variety laid open and exposing the contents in situ. Mears of Philadelphia reports a case of ovarian cyst removed from a girl of six and a half by Bradford of Kentucky in 1875. From this age on to adult life many similar cases are recorded. Nearly every medical museum has preserved specimens of dermoid cysts, and almost all physicians are well acquainted with their occurrence. The curious formations and contents and the bizarre shapes are of great variety. Graves mentions a dermoid cyst containing the left side of a human face, an eye, a molar tooth, and various bones. Dermoid cysts are found also in regions of the body quite remote from the ovary. The so-called "orbital wens" are true inclusion of the skin of a congenital origin, as are the nasal dermoids and some of the cysts of the neck.
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
