Epidermal inclusion cyst of the larynx.

Epidermal inclusion cyst (EIC) is a benign cyst filled with keratin fibers, which can develop in any part of the body. It is commonly seen in the skin, especially on the face, scalp, neck, and trunk, and has the tendency to slowly grow toward deeper epidermis parts and to cause cystic expansion. Epidermal inclusion cysts are not common in mucosal sites such as the larynx; however, these can arise owing to squamous metaplasia of the glands. We present a 52-year-old man with a laryngeal EIC. This is a very rare case in the literature of EIC in the larynx.
