Embryoma (or embryonal tumor) of the parotid gland: report of two cases.

Embryoma is the name applied by Vawter and Tefft to congenital tumors of the parotid gland. These tumors are highly uncommon, and they must not be confused with malignant tumors--i.e., cylindroma, embryonal carcinoma, or teratoma. Alone, complete surgical exeresis is necessary without radiation or chemotherapy. Two observations of embryoma are reported because of the diagnostic and therapeutic problems involved.
