Skin metastasis of prostatic carcinoma.Report of a case and statistical observation of skin metastasis of visceral cancer at Univ. of Tsukuba.

A case of prostatic carcinoma with skin metastases is reported. The patient showed four cutaneous nodules on the head. We biopsied one of them, and found out that it is skin metastases of an adenocarcinoma. After admission to Tsukuba Univ. Department of Dermatology, prostatic carcinoma was detected. Prostatic carcinoma rarely metastasizes to the skin, and it occupies less than 1% of the metastatic carcinoma of the skin.
