Abstract

Dermoid cysts are tumors composed of two germ layers-ectoderm and mesoderm. They are epithelial-lined cavities with skin appendages (hair, hair follicles, sebaceous glands, etc.). This distinguishes them from cholesteatomas, which are composed only of ectodermal elements, and teratomas, which are composed of ectodermal, mesodermal, and endodermal elements. Dermoid cysts can occur anywhere in the body where there is a fusion of embryologic tissues. About 7% of dermoids occur in the head and neck region. Fifty percent of these occur in the orbital region, 25% occur in the oral cavity, and 13% occur in the nasal cavity. Only a few cases of dermoids in the middle ear and mastoid have been reported. These are thought to arise at points of fusion of the first branchial cleft and groove.
