Paratesticular rhabdomyosarcoma of the young adult.

The authors report a case of paratesticular rhabdomyosarcoma in a young adult. This tumour is more frequent in children than in adults. Rhabdomyosarcoma is the commonest variety of soft tissue sarcoma in children and young adults. It represents 6.5% of all malignant tumours in paediatrics with an annual incidence of 4 to 7 cases/million children. The primary paratesticular site is considered to have a good prognosis in comparison with other rhabdomyosarcomas, despite the frequency of retroperitoneal lymph node invasion. This superficial sire allows rapid diagnosis and consequently often complete resection of the tumour. The multidisciplinary treatment of paratesticular rhabdomyosarcoma has improved control of the disease with a a-year survival of 80%.
