title: [Primary testicular rhabdomyosarcoma: A case report].
abstract: BACKGROUND
  Rhabdomyosarcoma is the most common sarcoma of soft tissues in childhood and adolescence, with an annual incidence of 4-7 cases per million children aged 15. Embryonal rhabdomyosarcoma is common in adults younger than 30 years, and are usually presented as a large painless, palpable mass (> 5cm). Survival in the case of paratesticular sarcoma in men is approximately 50%.
  
  
  METHODS
  Male 27 years of age with no history of importance, was seen in a clinic with an increased, painless, left testicular volume 3 years onset. Intrascrotal left testicle increased volume, with dimensions of 20×12×8cm, a stone and left inguinal node in induratum measuring 2×2cm. Microscopically, it showed a pattern of an embryonal rhabdomyosarcoma with left inguinal node metastases.
  
  
  CONCLUSIONS
  Early diagnosis of testicular tumours, and especially of primary intratesticular rhabdomyosarcomas, and aggressive surgical treatment in combination with chemotherapy reduces the incidence of local recurrence and may improve the rate of disease-free survival and overall survival in adult patients with metastases.
