Prostatic carcinoma is one of the most common malignancies in males of western countries but it is a rare malignancy in Korea. If it occurs, it commonly metastasizes to other organs. Inspite of its high incidence of distant metastasis, the cutaneous metastasis of the prostatic carcinoma is very rare and seems to have a poor prognosis. A 67-year-old man presented multiple nontender nodules on the skin of the right thigh and had episodes of multiple metastases from prostatic carcinoma to the lungs and bones. Histopathologic findings of the skin showed atypical cells infiltration at the dermis. Immunohistochemical staining for prostate specific antigen showed a positive reaction, therefore, we reached the diagnosis of cutaneous metastasis from prostatic carcinoma.
