Cutaneous metastases from prostatic carcinoma

Cutaneous metastasis from carcinoma of the prostate is a rare phenomenon. When it occurs, metastases usually appear as multiple nodules involving the suprapubic area and the anterior aspect of the thighs. We report on two cases of cutaneous metastases from prostatic carcinoma, one of them presenting the stereotypical clinical and histopathological findings, whereas in the other one cutaneous metastasis consisted of a morphea‐like plaque on the chest. Histopathologically, the later case revealed accumulations of neoplastic cells distributed in a folliculotropic pattern. In both examples immunohistochemical study with prostatic specific antigen (PSA) confirmed the prostatic origin of the metastases. We review the literature on this subject. © 1996 Wiley‐Liss, Inc.
