Metastasis of prostate gland adenocarcinoma to penile and scrotal cutaneous tissues.

The metastatic sites of adenocarcinoma of the prostate are well documented. Bone metastasis is the most frequently encountered site. Skin metastasis is rarely reported. Its presence, however, is associated with a poor prognosis. The possible cause of cutaneous spread is discussed in the case report. The possible role that external-beam radiotherapy may play in this setting is also analyzed.
