title: A rare occurrence of intramasseteric schwannoma - case report and literature review.
abstract: A schwannoma is a benign, solitary, well-defined, painless, slowly-enlarging nerve sheath tumor, composed of Schwann cells. Intramasseteric localization is very unusual. We report the case of a 33-year-old male who developed an intramasseteric schwannoma. Tumor could be completely removed under general anesthesia. Histopathological examination made the diagnosis of intramasseteric schwannoma through the presence of Antoni A areas and Verocay bodies. The diagnosis of schwannoma should be taken into consideration in case of parotideomasseteric tumors.
