Pleomorphic adenoma of deep lobe of parotid: A rare pediatric tumor

Extracapsular Dissection for Small Benign Tumors of Parotid Gland: A Case Report on Contemporary Technique

“…The myoepithelial cell is thought to be the cell of origin capable of producing such a variety of morphological diversity. Histopathologically, PA consists of the duct-like structure made up of epithelial cells with the association of non-ductal cells, i.e., myoepithelial cells, within a heterogeneous stromal background myxoid, chondroid, and osseous differentiated structure [3,10]. The parotid gland neoplasms' differential diagnosis needs to include benign lesions like Warthin tumor, myoepithelioma, and basal cell adenoma (BCA).…”

“…Additionally, malignant salivary gland tumors, including mucoepidermoid, adenoid cystic, and acinic cell carcinomas, need to be considered. Non-salivary gland neoplasms known to arise in the parotid gland include hemangioma, lymphangioma, lymphoma, and lipomas within the parotid lymph nodes [3].…”

“…Pleomorphic adenoma (PA) is a true neoplasm that will continue to grow or regrow, if not completely removed [1,2]. It is one of the most commonly seen salivary gland neoplasms accounting for 53-77% of parotid tumors, and 1.5-23% of cases of recurrent PA undergo malignant changes [3,4]. Around 80% of all PAs develop from the parotid gland superficial lobe, presenting as firm and freely movable mass [3].…”

Around 80% of all PAs develop from the parotid gland superficial lobe, presenting as firm and freely movable mass [3]. It usually goes unrecognized for many years, when it arises from the parotid gland's deep lobe until the size creates dysphagia or gagging symptoms [3,5].…”

The majority of these tumors are slow-growing, painless, and usually lateral to the facial nerve.…”
