Abstract
Meningiomas are tumors of the central nervous system that rarely present as extracranial soft tissue masses. Meningioma of the skin is referred to as cutaneous meningioma. Cutaneous meningioma of the scalp is extremely rare and may cause diagnostic challenges. A 70-year-old female patient presented with a painless mass on her scalp. A punch biopsy was performed; histological examination of the specimen revealed an infiltration of spindle-shaped and epithelioid atypical cells arranged in whorls. Immunohistochemistry was positive for vimentin and epithelial membrane antigen. On magnetic resonance imaging, a large intracranial mass eroding through the skull was observed. A diagnosis of intracranial anaplastic meningioma was established and excision was performed in the Department of Neurosurgery. It is important to consider intracranial tumors in the differential diagnosis of nodules on scalp.
