What is the most common benign salivary gland tumor?

• A. Cystadenoma
• B. Pleomorphic adenoma
• C. Warthin's tumor
• D. Mucoepidermoid carcinoma

Answer: (B)

Pleomorphic adenoma is recognized as the most common benign tumor of the salivary glands. This tumor is characterized by its mixed cellular composition, which includes both epithelial and mesenchymal components, hence the term "pleomorphic" that denotes variability in the cell types present. This tumor typically arises in the parotid gland but can also occur in other salivary glands. Clinically, it often presents as a painless, slow-growing mass. Its benign nature means that while it may cause aesthetic concerns or functional impairments as it grows, it does not spread to other body parts, and complete surgical excision generally leads to excellent outcomes. The other options represent different types of salivary gland tumors. Cystadenoma, while a benign tumor, is much less common than pleomorphic adenoma and typically refers to a glandular cystic growth. Warthin's tumor, also a benign salivary gland tumor, occurs primarily in the parotid gland but is less prevalent compared to pleomorphic adenoma. Mucoepidermoid carcinoma is a malignant neoplasm, contrasting with the benign nature of pleomorphic adenoma. Therefore, pleomorphic adenoma stands out for its frequency and benign characteristics among salivary gland
