We here report two cases of solitary fibrous tumor (SFT) arising in the prostate. Two men, 66 and 69 years old, with urinary tract symptoms were diagnosed with SFT on transrectal needle biopsy and transurethral resection of the prostate, respectively. The tumors were removed by a low anterior resection including tumor, prostate and rectum en bloc and cystoprostatectomy, respectively. Both tumors were well‐circumscribed but also showed some infiltration of the prostate glands. They were composed of storiform bundles of bland spindle cells that stained strongly for CD34 and vimentin but negative for muscle markers. Although rare, SFT should be considered as differential diagnosis of spindle cell lesions on prostate biopsies.
