Prostatic adenocarcinoma with cutaneous metastases overlying oestrogen-induced gynaecomastia

Carcinoma of the prostate gland is the second most frequent malignancy in males, accounting for 17% of cancer in men; between a third and one-half of these patients will have distant metastases at onset, but rarely cutaneous. We now report a case of prostatic adenocarcinoma with such metastases involving the right nipple and periareolar skin, overlying an area of hormone-induced gynaecomastia.
