Intracranial Pleomorphic Malignant Fibrous Histiocytoma, Associated to Systemic Lupus Erythematous: A Case Report

Background: Pleomorphic Malignant Fibrous histiocytoma (MFH) is a rare neoplasms of the soft tissue and bone composed of fibroblastic and histiocytic components with mitosis figures, nuclear pleomorphism and anaplasia.

Case Presentation: We presented a rare case of MFH in 44 year old woman with history of systemic erythematosus lupus and seizures. Treated with prednisone. The cerebral TAC showed a temporal mass. Craniotomy was performed and the examination of the biopsy sample revealed a giant, pleomorphic and atypical cells. Immunohistochemical analysis showed positivity for vimentin, CD68, Fascin, lysosyme and MIB-1 labeling index of 20%. Pleomorphic malignant fibrous histiocytoma was diagnosed, with involvement of the overlying temporal lobe. We report a case of MFH of the left temporal in adult.

Discussion: The neuroimaging and intra-operative opinion were of a meningioma. Histopathology, in conjunction with immunohistochemical evaluation and proliferation marker, confirmed the diagnosis. This is the firth case reported of PMFH associated to systemic lupus erythematous and different histological patterns.
