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.
