Cutaneous metastases from prostatic cancer.

The skin is involved in metastases from 2-9% of malignant tumors. These usually tend to spread to the skin relatively late in the course of the disease. Skin metastases of prostatic origin are quite uncommon and preferentially localized to the lower abdomen and genital area. We present a case of cutaneous metastasis from prostatic adenocarcinoma that preceded diagnosis of the primary tumor and was located on the neck.
