title: [Abdominal wall soft tissue perineurioma. Autopsy findings and review of the literature].
abstract: The perineuroma is a rare benign tumor, derived from nerve sheath perineurial cells. It was first described in 1978 by Lazarus and Trombetta, who based their diagnosis on the ultrastructural features of perineurioma cells. Subsequently, the immunohistochemical profile of perineurial cells allowed an easier diagnosis of this condition. A case of perineurioma in a 47-year-old woman is reported. The patient presented with an abdominal wall mass, with aprevious diagnosis of malignant fibrous histiocytoma (MFH). The case was reviewed at an oncology hospital, inmunohistochemistry was performed and the concluding diagnosis was soft tissue perineurioma.
