Abstract

Rhabdomyosarcoma is a malignant tumor resulting from the abnormal proliferation of rhabdomyoblasts, which can grow in any part of body that contains embryonal mesenchyme. In general, rhabdomyosarcomas account for 5-10% of all childhood tumors. Of the rhabdomyosarcomas, genitourinary tumors account for approximately 20% of all human rhabdomyosarcomas, but only 7% of all rhabdomyosarcomas are of paratesticular origin. In the Korean literature, only two cases of paratesticular rhabdomyosarcomas in children have been reported. Herein, two cases of unilateral paratesticular rhabdomyosarcomas in children, successfully treated with a radical orchiectomy and chemotherapy, are reported. (Korean J Urol 2004;45:1072-1076)
