Abstract

The differential diagnosis for scalp lesions is broad, ranging from simple cysts to tumors. We present the case of a 49-year-old woman with a scalp lesion initially suspected to be an epidermoid cyst but later diagnosed as cutaneous meningioma on biopsy. As a rare form of extracranial meningioma, this case underscores the importance of correlating clinical findings with histopathology, such as integrating morphological features, immunohistochemical markers, and molecular studies, to establish a diagnosis in challenging cases with inconclusive clinical or radiological findings.
