Epidermal growth factor receptor overexpressed malignant fibrous histiocytoma associated with recurrent meningothelial meningioma

Neurol Med Chir (Tokyo). 2009 Nov;49(11):523-7. doi: 10.2176/nmc.49.523.

Abstract

A 71-year-old woman presented with a rare case of malignant fibrous histiocytoma (MFH) associated with recurrent meningothelial meningioma. The neuroimaging findings were consistent with a diagnosis of recurrent meningioma. Surgical removal was performed. Histological and immunohistochemical examinations detected meningothelial and MFH tumor components. The MFH component showed diffuse 3+ staining for epidermal growth factor receptor protein, predominantly located on the cell membrane and to a lesser extent within the cytoplasm. However, a fluorescein isothiocyanate analysis detected no amplification of epidermal growth factor receptor gene.
