Solitary Fibrous Tumor/Hemangiopericytoma of the Penis: Report of the First Case

Hemangiopericytoma (HPC) is an uncommon perivascular tumor, first described in 1942, occurring most frequently in the extremities (pelvis, meninges, head and neck), and rarely affecting the urogenital system. In 1870, Wagner published the first histological description of a Solitary Fibrous Tumor (SFT) of the pleura. It is now thought that the majority of lesions previously called hemangiopericytomas (HPCs) are essentially indistinguishable from solitary fibrous tumors (SFTs). Nowadays, the new WHO classification of soft tissue tumors categorizes most HPCs as SFTs. We report the first case of penile SFT-HPC in a 44-year-old man, presenting with a 3-year history of slow-growing penile mass. The patient underwent a tumor excision. Six months after surgery he is free of local recurrence and distant metastasis.
