Images – A case of total laparoscopic resection of a giant solitary fibrous tumor of the seminal vesicle: A rare tumor that causes frequent micturition and abdominal pain

摘要

Solitary fibrous tumors (SFTs) are a rare type of tumor originating from CD34+ dendritic mesenchymal spindle cells that exhibit fibroblast differentiation. These lesions mainly originate from the visceral pleura and rarely occur outside the pleura, but they can occur in any part of the body. Most lesions are benign, and malignancy is extremely rare. For this type of lesion, the diagnosis relies on pathology, especially immunohistochemical examination.
