Introduction
Primary extracranial and extraspinal meningioma is a rare tumor which is usually limited to head, neck or paravertebral soft tissues. Case report: This is the report of a 47-year-old man with a swelling on the right side of his face over the mandibular area. On examination a mass with firm consistency and an approximate diameter of 4 cm was found. Panoramic X-ray showed a unilacular well-defined radiolucency with a cortical border at mandibular ramus area. The lesion was then surgically excisedConclusion
Histologically, proliferation of uniform spindle cells in the whorled and fascicular pattern was seen. Immunohistochemicall study revealed tumor cells positive for Epithelial Membrane Antigen and Vimentin, but showing no reaction for cytokeratin, S-100 and ki-67. A diagnosis of ectopic meningioma with transitional pattern predominance was established according to histopathological and immnuohistochemical features of the mass.Language:
