Al-Motairi YR 2015 UL http://smj.org.sa/content/36/2/236.abstract AB Solitary fibrous tumors (SFT) of the upper limb are extremely rare, and we report this tumor in the arm of a 30-year-old male. He is presented with a 22 cm painless mass. Complete surgical excision was performed. The histological diagnosis of SFT was based on the presence of ectatic blood vessels and positive staining for CD34 and vimentin. He remains disease-free at the 3-year follow-up interval. The report aims to increase the awareness of the criteria for the histological diagnosis of SFT, as well as the principles of their surgical excision and follow-up.
