Solitary fibrous tumor of the inguinal region: a clinicopathological, light-microscopic, immunohistochemical, electron microscopic and flow-cytometric DNA study.

摘要

Solitary fibrous tumors (SFTs) are rare neoplasms with a probable mesenchymal origin that were first reported in the pleura but can occur in different sites. We report a case of SFT arising in the inguinal region of a 55-year-old woman. The patient presented with a mass in the left groin; she underwent wide excision of the lesion which was well-circumscribed and without evidence of adjacent soft tissue involvement. The histological, immunohistochemical and electron microscopic criteria for SFT were found. She had an uneventful recovery and she is alive without evidence of disease five years after operation. To our knowledge, this neoplasm has never been reported in this location.
