A case of cutaneous metastases from prostate cancer.

We report a case of cutaneous metastasis of prostate cancer, A 73-year-old man had a nodular lesion in a chest tumor. Aspiration cytology showed a cribriform pattern of tumor cells with oval and round nuclei and fine granular chromatin. Histologically, the tumor consisted of various-sized glands and cribriform structures. Immunohistochemical staining for prostate-specific antigen was positive in tumor cells and confirmed in transrectal biopsy of the prostate. When aspiration cytology is used in cutaneous tumors, prostate cancer should be considered as a differential diagnosis.
