Cutaneous metastasis from internal malignacy is recognized but infrequently occuring manifestation. The prostatic carcinoma rarely acts as a primary source for cutaneous metastasis. We report a case of cutaneous metstasis from prostatic carcinoma. A 82-year-old male presents multiple painless erythematous nodules on suprapubic area, having an episode of surgical removal of prostate carcinoma two years ago. Histologic finding shows atypical anaplastic cell infiltration at the dermis and subcutaneous tissue, forming dermal tumor island, and have features similar to primary prostatic carcinoma. Immunohistochemical staining for prostate specific antigen shows positive reaction within cells, can assist in localization of the metatatic adenocarcinoma to a prostate origin.
