title: [Atypical fibrous histiocytoma of the seminal vesicle].
abstract: OBJECTIVE
  To describe a rare case of fibrous histiocytoma of the seminal vesicles.
  
  
  METHODS
  A tumor occupying the entire hypogastrium, extending beyond the umbilical region were the only remarkable findings in our 47-year-old male patient that prompted us to perform complementary studies such as US, contrast-enhanced radiological evaluation (urography, cystography, colon enema and intestinal transit time) and laparoscopy that disclosed an extraperitoneal tumor with no precise location. A large tumor involving the seminal vesicles was found at surgery and resected. The histological analyses disclosed an atypical fibrous histiocytoma of the seminal vesicles.
  
  
  RESULTS
  Patient outcome was satisfactory.
  
  
  CONCLUSIONS
  Because tumors of the seminal vesicles are uncommon, it is practically impossible to diagnose this tumor type preoperatively.
