Unusual neck mass in an adolescent: benign basal cell adenoma of the minor salivary glands of the piriform sinus.

With an incidence of less than 3%, salivary gland tumors are rare in the head and neck. The percentage of basal cell adenomas within the group of salivary gland tumors is even less (0.2-2%). Salivary gland tumors occur very rarely in adolescents. The basal cell adenoma commonly affects older persons and occurs most frequently in the major salivary glands. We present the unusual case of a benign basal cell adenoma of the minor salivary glands of the piriform sinus in a 14 year old male patient. Unusual are the age of the patient, the histological type, size and localisation of the tumor.
