Case Report: Rare site for intraoral meningioma [version 1; peer review: 2 approved with reservations]

Extracranial meningioma is very rare with few cases reported, especially in the oral cavity. Its diagnosis considered a challenge owing to the unusual site of occurrence. We report, to our knowledge, the first case of extra-cranial meningioma as a primary tumor in the palate with no detected intracranial extension. A 59-year-old female Egyptian patient presented with a 22-year history of a large painless swelling at the right side of the palate, which could not be seen on radiographs. An incisional biopsy was taken and, after assessment with a panel of immunohistochemical markers, the lesion was diagnosed as extracranical meningioma. The patient did not show up for surgical excision and follow-up was not performed because of loose of contact with the patient. Intraoral meningioma is a rare unsuspected tumor. Immuohistochemical markers are important when confirming this diagnosis.
