Abstract
Neurofibromatosis-1 has a known increased risk of malignancy with rhabdomyosarcoma occurring in up to 6% of patients. Here we report on an 8-year-old male with a history of Neurofibromatosis-1 and previously treated stage 3, group III bladder/prostate embryonal rhabdomyosarcoma (diagnosed at 18 months old) who presented with penile swelling concerning for priapism. Imaging and subsequent biopsy confirmed embryonal rhabdomyosarcoma of the penile corporal bodies. Penile rhabdomyosarcoma is exceedingly rare, with less than 15 case reports in the literature. Our patient received chemoradiation per D9803 with organ preserving local control and is doing well 3 months after treatment.
