RESUMEN
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. An 18-year-old man presented with a painless left scrotal mass and lump abdomen that had evolved over four months. A histological examination of the lesion revealed rhabdomyosarcoma. Chemotherapy with alternative cycles of Vincristine, Adriamycin, Cyclophosphamide followed by Ifosphamide, Etoposide was given. 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.
