A case of prostatic rhabdomyosarcoma associated with multilocular cyst is reported. A 31-year-old man with pollakisuria was found to have a multilocular cyst at the prostate by initial ultrasonogram. Although the cyst was growing gradually showing a likelihood of malignancy, multiple biopsies of the cyst failed to prove malignancy. About 40 months after the first examination, a solid tumor appeared in the cyst on the ultrasonogram and pathologically it was rhabdomyosarcoma. Unfortunately, he had already developed multiple metastases by this time. Systemic CYVADIC chemotherapy and radiation to the whole pelvis were commenced. Initially, the lung metastases responded well to CYVADIC chemotherapy. However, he died from a worsening of the multiple lung and bone metastases 5 months after the treatment.
