후이개 부위에 발생한 유피낭 1예

Dermoid cysts are unusual neoplasms that are often diagnosed during childhood. They are derived from both ectoderm and mesoderm. Keratinizing squamous epithelium is present together with dermal derivatives such as hair follicles, smooth muscle, sweat and sebaceous glands, and fibroadipose tissue. Dermoid cysts of head and neck area are very rare, especially in postauricular area. Recently we experienced a case of postauricular dermoid cyst, therefore we report a case along with review of literature. (J Clinical Otolaryngol 2006;17:273-276)
