A 40-year-old male was admitted to the Department of Otolaryngology, Mie University Hospital on January 29, 1979 because of a mass in the left infra-auricular region of six years' duration. There were pain and left facial paralysis. The patient first noticed a mass, a golf-ball in size, in the left parotid region in 1974. The mass was incised and drained, and it disappeared. In December 1978 a mass developed in the same region and was biopsied. Histopathologically chronic inflammatory change was obtained. Eight months later, the mass rapidly increased in size and the patient developed left facial paralysis. On admission, the mass, measuring 4×5×5cm, was hard, tender and fixed to the deep structure and skin. On February 16, 1979 under general anesthesia the mass in the parotid region was surgically excised through an S-shaped skin incision. After lateral lobectomy a capsulated tumor mass was found in the deep lobe of the parotid gland. The main trunk of the facial nerve was firmly adherent to the tumor. Because the buccal branch was encompassed by the tumor, it had to be sacrificed.The removed tumor was 6.5×5×4cm in size and weighed 115g. It contained about 90ml of a gray gruel-like substance containing hairs. Although the stratified squamous epithelium was noted without skin appendages on histopathological examination in the cyst wall and the muscle structure, the final diagnosis was dermoid cyst developing in the deep lobe of the left parotid gland.Etiology and statistics of this cyst in the head and neck were discussed.
