Cutaneous and subcutaneous metastases from carcinoma of prostate.

Secondary cutaneous and subcutaneous metastases originating from a visceral carcinoma are relatively uncommon and are associated most frequently with mammary, pulmonary, renal, and colonic cancers. Cutaneous and subcutaneous deposits from cancer of the prostate must be classified as extremely rare, e.g., only one solitary cutaneous metastatic carcinoma of prostatic origin was seen among 136,017 surgical and postmortem specimens submitted to the department of pathology at UCLA Hospital from male patient thirty-five years of age and older during the years between 1955 and 1980. Recently we observed a second case. A discussion of these 2 cases and a review of the English literature are reported.
