Schwannoma in the Mandibular Canal: an Unusual Presentation, Management, and Review of Literature
摘要
Schwannoma, also known as neurilemmoma or neurinoma, is a rare benign neural tumor arising from Schwann cells of the peripheral nerve sheath. In the oral cavity, schwannomas may develop in both soft tissue and intraosseous sites. Intraosseous schwannomas most commonly occur in the posterior mandible, typically presenting as unilocular or multilocular radiolucencies on radiographs. Among intraoral soft tissue sites, the tongue is the most frequently involved location, followed by the palate, buccal mucosa, and lips. Although rare, schwannomas should be considered in the differential diagnosis of oral cavity tumors due to their potential to mimic more common odontogenic or non-odontogenic lesions. A definitive diagnosis requires thorough clinical evaluation supplemented by histopathological examination and immunohistochemical analysis.
MethodologyWe report a unique case of a male patient presenting with swelling on the left side of the jaw and an intraoral submucosal bulge. Initially suspected to be an odontogenic tumor, further investigation revealed the lesion to be a schwannoma arising from the mandibular canal, likely originating from the inferior alveolar nerve. We conducted a review of the current literature on schwannoma affecting the mandibular canal.
ConclusionThe case underscores the importance of considering neural tumors in the diagnostic work-up of jaw lesions and highlights the surgical approach to managing mandibular schwannoma.
