title: [Giant bizarre scrotal leiomyoma].
abstract: OBJECTIVE
  To review the diagnosis and therapeutic management of scrotal wall smooth muscle tumors by reporting an illustrative case. To emphasize that despite their histological characteristics on presentation, compatible with malignancy, these tumors have a benign behaviour, even when their size is much bigger than the ones found in the review bibliography.
  
  
  METHODS
  75-year-old male who presented a big, very slowly growing, painless, mobile, hard, not adhered to deep layers, non transilluminating scrotal tumor.
  
  
  RESULTS
  Pathology reported a giant bizarre scrotal leiomyoma.
  
  
  CONCLUSIONS
  We emphasize the atypical characteristics of this case, which despite its compliance with almost all classical criteria establishing the malignant character of tumor lesions has a benign behaviour. It complies with the criterion that, accordingly to reviewed bibliography, seems to be the most important to determine it: the absence of mitosis. We also insist on the importance of an adequate diagnostic approach which guarantees a proper surgical approach, for which we think ultrasound is essential.
