A clinical case report of priapism treated with external RT.

The aim of this short communication is to present an extremely uncommon case of penile metastases from rectal adenocarcinoma treated with an external beam radiotherapy technique. A 76-year-old man affected by very painful priapism from penile metastases was treated with radiotherapy (30 Gy) for symptom relief. In the course of the radiotherapy treatment the patient reported gradual and continuous pain reduction. One month after the end of radiotherapy both the priapism and the pain had disappeared. Although the long-term prognosis remains poor, good quality of life was achieved in this patient.
