- Extra-thoracic Solitary Fibrous Tumour, Malignant
Submitted by: Dr. Françoise Collin
A 32-year-old man presented with urine retention. CT scan and MRI were performed. They revealed a large pelvic mass with well-defined margins, located in the presacral area. The rectum was displaced laterally, and the bladder was pushed forward. Sacral bone was uninvolved. A well-circumscribed and partially encapsulated tumor measuring 14 x 10 x 6 cm was resected. On cut section, it was made of a white-gray fibrous-appearing focally nodular tissue with a firm consistency. There were scattered hemorrhagic changes. Three years later, the tumor recurred as a 6.5 cm mass in the retroperitoneum.
