title: [Diagnosis and differential diagnosis of squamous epithelial metaplasia in the parotid gland].
abstract: The authors report a case of proliferating squamous epithelium in the necrotic edge of multifocal oncocytic adenomatous hyperplasia of the parotid gland. A correct histological diagnosis is of great clinical relevance and difficulty, since similar findings can occur in mucoepidermoid carcinoma. The various cell types in the parotid gland and their roles in neoplasia are discussed.
