Dermoid cyst and epidermoid cyst generally occur in the anal region and ovary, and occurrence in the oral region is relatively rare. The authors reported in the literature a case of large epidermoid cyst in the floor of the mouth.<BR>The patient, a 55-year-old man, noticed a mass in the floor of the mouth during childhood. The mass gradually enlarged. At the initial consultation he complained of motor disturbance of the tongue and speech difficulties. Using general nasoendotracheal anesthesia, the mass, which had invaded the submental region through the mylohyoid muscle, was extirpated by the intra-oral method. The specimen measured, 8×6×3.5 cm, was ovoid shaped and weighed 120g. Microscopically, the cystic wall was found to be composed of keratinized squamous epithelium and connective tissue, but did not contain skin inclusions. Based on histological findings, a diagnosis of epidermoid cyst was established.
