摘要
Benign schwannomas are uncommon and their intraosseous location is even rarer counting for less than 1% of all benign primary bone tumors. They exceptionally occur in the oral cavity with the tongue being the most common site of involvement. We report here a case of intramandibular schwannoma derived from the inferior alveolar nerve, in a 57-year-old patient with a 3 months history of inferior left lip paresthesia. The oral examination showed a firm, painless and non-pulsatile swelling located in the inferior vestibule. The panoramic X-ray revealed a circumscribed and homogeneous radiolucent image. Treatment consisted of total excision of the tumor with preservation of the nerve bundles. The histological examination confirmed the diagnosis of schwannoma, The patient recovered a normal sensory function 6 months post-operatively without any recurrence up to 2 years after surgery. The treatment of intramandibular schwannoma is basically surgical with the conservative approach being the most advocated by majority of authors.
