Urogenital localization is rare, and only small numbers of cases of paratesticular SFT have been reported. An 81-year-old male with a history of colon carcinoma and complaint of testis swelling was referred for evaluation of a right paratesticular mass. Physical examination revealed a 2 cm oval-shaped paratesticular mass and herniation of intestinal loops in the right inguinal region after cough and Valsalva maneuver. An ultrasound examination was found in the upper pole of testis a well-defined hypoechoic mass in favor of testicular mass. It also revealed moderate to severe bilateral hydrocele and calcified wall in favor of benign lesion. In conclusion, SFT should be considered in the differential diagnosis of paratesticular masses and needs to be confirmed by IHC. CD34 and CD99 biomarkers are useful for confirmation of SFT. }, URL = {http://ijbc.ir/article-1-922-en.html}, eprint = {http://ijbc.ir/article-1-922-en.pdf}, journal = {Iranian Journal of Blood and Cancer}, doi = {}, year = {2020} }
