title: Mixed-type paratesticular rhabdomyosarcoma--a case report.
abstract: Rhabdomyosarcoma (RMS) is the most common soft tissue tumor of childhood; about 80% of cases occur before the age of 21 with the remaining 20% evenly spread throughout the remaining decades. A primary paratesticular site is considered to have a good prognosis in comparison with other RMS sites. Histologically, any subtype of RMS, including alveolar, pleomorphic, embryonal, and mixed type, may occur in the paratesticular region, but only a relatively small number of cases are mixed and this variant has a poor prognosis. We report a case of paratesticular RMS (mixed embryonal and alveolar type) in a 16-year-old boy.
