8.1 Pediatric Salivary Gland Neoplasms Salivary neoplasms are uncommon in children. They may arise in the acini and ducts (epithelial tumors) or in mesenchymal tissue, e.g., the intraparotid lymphoid (lymphoma)…

Introduction Chronic sialadenitis is the most common benign disease of the major salivary glands and is usually the result of obstruction of salivary flow due to calculi, strictures, or both….
