title: Embryonic paratesticular rhabdomyosarcoma: a case report.
abstract: BACKGROUND
  An embryonic paratesticular rhabdomyosarcoma is a very rare mesenchymal tumor. It is an intrascrotal tumor that is localized in paratesticular structures such as the epididymis or spermatic cord. Rhabdomyosarcoma is most often observed in children and adolescents, presenting as a painless scrotal mass.
  
  
  METHODS
  Our patient was an 18-year-old Moroccan man who presented with a painless left scrotal mass that had evolved over four months. An inguinal orchiectomy was performed. A histological examination of the excised tissue revealed an embryonic rhabdomyosarcoma.Our patient had three sessions of chemotherapy with vincristine, actinomycin C and cyclophosphamide. Each chemotherapy session was conducted over five days, with a cycle of 21 days. Our patient was assessed two months after the last chemotherapy session and demonstrated good clinical improvement.
  
  
  CONCLUSIONS
  Paratesticular rhabdomyosarcoma is a rare aggressive tumor manifesting in children and very young adults. Localized forms have a good prognosis whereas metastatic tumors show very poor results. A well-defined treatment based on surgery and chemotherapy yields good results.
