[Paratesticular embryonal rhabdomyosarcoma: report of 5 cases and review of the literature].

Objective:To improve the diagnosis and treatment of paratesticular embryonal rhabdomyosarcoma(PER).Methods:We retrospectively studied the clinical data of 5 cases of PER treated from 1997 to 2009 and reviewed the relevant literature,focusing on its clinical manifestations,diagnosis and treatment.Results:The 5 cases of PER,2 involving the spermatic cord,2 the testis and 1 the tunica vaginalis,were all treated by radical orchiectomy.Pathologically,2 cases were classified as stage I,1 as stage Ⅱ and 2 as stage Ⅳ.Postoperatively,2 of the patients received chemotherapy and the other 3 refused adjunctive therapy.The patients were followed up for 6,12,18 and 28 months,respectively.Four of them remained free from relapse and metastasis,and 1 stage Ⅳ patient died of multiple metastasis at 6 months.Conclusion:Early diagnosis,radical orchiectomy and adjunctive chemo-or radio-therapy are effective means to the treatment of PER.Natl J Androl,2010,16(9):840-843
