A renal solitary fibrous tumor (SFT) is an unusual and especially rare entity. Preoperative diagnosis usually difficult, but it remains of favorable prognosis. In this study, the authors report a case 33-year-old Moroccan man with history left pyelolithotomy who presented 19 cm mass associated two kidney stones in lower calyx. He underwent open radical nephrectomy, pathology revealed SFT. To be...

INTRODUCTION Solitary fibrous tumors are uncommon soft tissue tumors initially reported only in the pleura but, in recent years, they have been described at many extra pleural sites, such as mediastinum. The treatment of choice is the extensive surgical resection that is curative for most benign lesions. PRESENTATION OF THE CASE We present the case of solitary fibrous tumor of the anterior me...

Solitary fibrous tumors of the bladder are extremely rare especially in the females. This is the third case of SFT in a female urinary bladder. We are presenting a case of 36-years-old female who underwent a procedure for what thought to be cervical myoma. Cystectomy and bilateral ureteral re-implantation were performed. Mass showed to be solitary fibrous tumor of the urinary bladder. These tum...

Although FDG PET is increasingly used for the staging of many types of sarcoma, little has been written regarding the FDG PET imaging characteristics of solitary fibrous tumor. We report a patient undergoing FDG PET/CT surveillance for squamous cell carcinoma of the tongue who was incidentally found to have two soft tissue masses in the retroperitoneum and pancreatic tail. Due to their low degr...

Establishing the etiology of a retroperitoneal tumor may be difficult due to close proximity of multiple organs. Evaluation of retroperitoneal tumors often leads to surgery, many times to obtain a definitive diagnosis and rule out malignancy. Calcifying fibrous tumors (CFT) are very rare soft tissue tumors occurring most often in young patients. They are most often found arising in the thoracic...

Solitary fibrous tumors of the pelvis are rare. We report the case of a 32-years-old patient who presented with abdominopelvic mass. The imaging studies showed a right adnexal mass of more than 10 cm. Exploratory laparotomy revealed a 20 cm mass at the Douglas pouch which was adhered to the posterior wall of the uterus. Complete resection of the mass was performed. Histological analysis showed ...

Solitary fibrous tumors are very rare neoplasms that seldomly appear in extra-serosal soft tissues. In such cases, an accurate preoperative diagnosis is often difficult and challenging, especially in extrapleural ones. Traditionally, extrapleural solitary fibrous tumours have been regarded as indolent neoplasms similar to their intra-thoracic counterparts, although there has been some evidence ...
