Distant Cutaneous Metastases of Prostate Cancer: A Report of 2 Cases

Cutaneous metastases of prostate cancer are extremely rare. We present 2 cases of distant cutaneous metastases at atypical locations of prostate adenocarcinoma, and highlight the value of 2 immunohistochemical stains—prostatic acid phosphatase and prostate-specific membrane antigen—that can aid diagnosis, particularly in cases with negative staining for prostate-specific antigen.
