Is there a difference between a Dermoid Sinus and a Dermoid Cyst?
Yes, the Dermoid cyst is encapsulated and often contains hair, or other material. It does not have the thread-like tube extending down into tissue or bone. The Dermoid Sinus is a tube-like opening which actually grows up from where it began in the embryonic stage. The tube can be of different lengths: thin as a piece of thread or thick as in spaghetti or cooked macaroni.
