Case Report - Subcutaneous metastasis as first evidence of prostatic cancer

A rare case of subcutaneous metastasis from prostatic cancer is presented. Swelling in left inguinal region proved to be adenocarcinoma consistent with carcinoma prostate on histopathology and immunohistochemistry. No primary was identified but was associated with raised prostate specific antigen. Poor response to hormonal ablation and rapid progression to death was observed. Cutaneous and subcutaneous metastases from prostatic cancer are rare. The case reported in the present paper, first evidence of a prostatic cancer, is even more exceptional. The literature on this rare presentation is briefly reviewed.
