Congenital Hybrid Basal Cell Adenoma—Adenoid Cystic Carcinoma of the Salivary Gland

Abstract

A congenital parotid gland tumor involving the facial nerve was excised, revealing histologic and ultrastructural features of a basal cell adenoma and adenoid cystic carcinoma. An asynchronous regional metastasis xvas successfully eradicated with adriamycin. Seven other similar appearing tumors occurring in neonates are documented in the literature and serve to establish this tumor as a clinicopathologic entity. The surrounding parotid gland had “d\s-plastic” changes attributed to obstruction during morphogenesis.
