Primary Cutaneous Meningioma arising from the Scalp: A case report

ABSTRACT

Primary cutaneous meningiomas are extremely rare tumors found in the cutis or subcutis, and generally have a benign course. The tend to be located on the scalp, face, neck. or paravertebral area. The primary cutaneous meningioma bears similarities to developmental defects and probably originates from arachnoid cell rests in the skin, although diverse groups of cutaneous meningiomas seem to arise from several different sources. A case of primary cutaneous meningioma occuring in the scalp of left parietal area of a 27-year-old female is presented. Clinically the lesion appeared as indolent, slow growing cutaneous mass and has no connection with underlying brain tissue, as determined by examination of the roentgenographs. The definite diagnosis was made after pathological examination. Microscopically the tumor is composed of sheets and nests of meningothelial cells. Immunohistochemical and electron microscopic studies reveal the typical findings of meningioma.
