Resection of Salivary Duct Carcinoma ex Pleomorphic Adenoma of Minor Salivary Gland of Parapharyngeal Space without Mandibular Osteotomy
Abstract Parapharyngeal space (PPS) tumors offer significant surgical challenges owing to their rarity, difficult anatomy, and presence of vascular structures nearby. Although most of the tumors in the prestyloid compartment of PPS are benign, malignant neoplasms have been reported infrequently. Pleomorphic adenoma, although the most common benign salivary gland tumor, is rarely found to arise from the minor salivary glands of PPS.
