title: Pleomorphic adenoma of the accessory parotid gland: case report and reappraisal of intraoral extracapsular dissection for management.
abstract: Pleomorphic adenoma is the most common tumor of the major and minor salivary glands. Rarely is it found evolving from an ectopic location of major salivary glandular tissue in the mid cheek. A healthy 56-year-old woman presented to our institution with a 20-year duration of a slowly growing right cheek soft tissue mass that was causing facial asymmetry. No significant functional or neurosensory dysfunction was appreciated. Radiologic examination showed a heterogeneous, hyperintense, well-delineated mass within the region of the right buccal fat pad. Fine-needle aspiration biopsy showed benign salivary gland elements consistent with pleomorphic adenoma. The decision was made to perform intraoral extracapsular dissection for removal. Discussion of the clinical assessment and magnetic resonance imaging evaluation with an emphasis on intraoral extracapsular dissection for definitive surgical therapy of longstanding benign salivary gland tumors is emphasized.
