Solitary Fibrous Tumour of Pelvic Soft Tissue Mimicking A Prostatic Mass: Diagnosis and Management

Author(s): Keval N Patel and Shashank J Pandya

Solitary fibrous tumor (SFT) is a rare soft tissue tumor occurring rarely in extrapleural sites like the pelvis. We here present a case of SFT of the pelvis which was initially diagnosed radiologically as a mass arising from prostate and on biopsy found to be a solitary fibrous tumor. On exploration, there was a well encapsulated tumor in retro-vesical space separate from prostate. Histopathology with Immuno-histochemistry confirmed the diagnosis of SFT. We retrospectively reviewed the literature to avoid such confusion in future. Pubmed search was made with the following keywords: solitary fibrous tumor, treatment, soft tissue, pelvis, radiology, and histopathology.
