Study Notes
- Pleomorphic salivary adenoma is the most common benign salivary gland tumor.
- Muco-epidermoid carcinoma is the most common malignant salivary tumor of the parotid gland.
- Other benign tumors of the parotid include Papillary cystadenoma lymphomatosum, Basal cell adenoma, and Oncocytoma.
- Other malignant tumors of the parotid include Adenoid cystic carcinoma, Acinic cell carcinoma, Adenocarcinoma, and Squamous cell carcinoma.
- The parotid gland is the largest of the 3 major salivary glands and is bounded by the zygomatic arch, masseter muscle, external ear, sternocleidomastoid muscle, and inferior body of the mandible.
- The parotid gland receives its blood supply from branches of the external carotid artery and its sensory innervation from the auriculotemporal nerve and greater auricular nerve.
- The risk factors for developing malignant salivary gland tumors include smoking, previous Epstein-barr infection, and radiation exposure.
- Parotid swelling often presents as a slow-growing painless mass, smooth, firm lobulated mobile swelling, and positive curtain sign.
- Features of malignancy include recent increase in size, pain, nodularity, involvement of skin, LN, facial nerve, masseter, and restriction of jaw movement.
- Surgical excision is the preferred management for pleomorphic salivary adenomas due to the potential for malignant transformation.
