ubtedly 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 nea
