Evaluation and Diagnosis of Salivary Gland Neoplasms

Salivary gland tumors are an uncommon heterogeneous group of neoplasms that vary in their anatomic site, histology and biologic behavior. Pleomorphic adenoma is the most common benign tumor and mucoepidermoid and adenoid cystic carcinoma are the most common malignant tumors. Evaluation and diagnosis of these tumors includes not only a complete history and head and neck exam, but also biopsy and imaging of the tumors. Controversy remains regarding the necessity and type of biopsy to be performed and the usefulness of imaging.
