Prostatic rhabdomyosarcoma in the adult, A case report.

Prostate embryonal rhabdomyosarcoma (ERMS) is a common tumour in infants and children, but it is rare in adults. It is characterized by a high degree of malignancy, both local rapid growth with formation of large pelvic masses, often leading to renal failure due to bladder outlet obstruction, and systemic spread, commonly to the lungs, liver and bone. We report on a case of a stage III prostate ERMS, approached with combined-modality treatment, with the administration of 5 courses of doxorubicin, ifosfamide and 2-mercaptoethane sulfonate sodium (mesna), with planned subsequent radiotherapy to the prostatic bed (60 Gy/30 fractions).
