Abstract
Solitary fibrous tumors (SFTs) are rare mesenchymal tumors, usually described at the pleura level, but since they can develop in different extra pleural locations. Retroperitoneal location is rarely described.
The anatomopathological study remains the key to the diagnosis of SFT, the curative treatment is based on surgical excision. Most extra-thoracic SFT are benign, but may recur or metastasize after complete removal, even in the absence of histopathological evidence of malignancy. Careful long-term monitoring is therefore recommended.
We report the case of retroperitoneal SFT in a 70-year-old male who was consulting for generalized abdominal pain. The aspects of imaging, anatomopathology and immunohistochemistry are detailed.
Keywords: Solitary fibrous tumor, retroperitoneum, immunohistochemistry, surgery.
