Extract

Prostate cancer is the most frequent internal malignant neoplasm in men, but it represents only a minority of cutaneous metastases. In a meta-analysis of cutaneous metastasis, Krathen et al1 report that the overall incidence of cutaneous metastases from visceral cancers appears to be around 5%. The highest incidence of cutaneous metastasis was seen in breast cancer, occurring with an incidence of 24%. In the same meta-analysis, prostate cancer was the least likely visceral malignant neoplasm to metastasize to the skin (0.7% incidence).1 Herein, we describe a patient with multiple cutaneous nodules as the presenting sign of recurrent prostate cancer.
