Solitary Fibrous Tumor of the Abdominal Wall

Abstract

Solitary fibrous tumor is a rare neoplasm of mesenchymal origin that usually arise within the pleura. Its origin in abdominal wall is extremely rare, with only 15 cases described in the English literature.We report the case of a 55-year-old woman presented with a mass located at the left lower quadrant of the abdominal wall. Microscopic studies revealed histologic and immunohistochemical features consistent with a SFT. Eighteen months after surgical excision of the mass followed by adjuvant radiotherapy, the patient is alive and disease-free. The authors discuss the clinicopathological features of SFTs, differential diagnosis and treatment options.
