Pseudosarcomatous fibromyxoid tumor of the prostate. A case report with review of the literature.
A previously healthy 42-year-old white male presented with urinary obstruction. Radiographic evaluation revealed a 4-cm prostatic mass extending into the bladder. Transrectal biopsies revealed a sarcomatoid histology with atypical spindle cells suspicious for possible sarcoma. A transurethral resection of the prostate was performed revealing a benign fibromyxoid lesion with spindle cell proliferation. Postoperatively, the patient voided normally with no evidence of recurrence on follow-up of over 1 year. The clinical presentation and histologic features are consistent with pseudosarcomatous fibromyxoid tumor, a rare but benign lesion which has previously been mistaken for a malignant prostatic sarcoma. It is important for the urologist to recognize this benign process so that radical procedures are not performed.
