Cutaneous metastasis: An unusual presenting feature of urologic malignancies

Abstract

Urological malignancies are well known for their ability to metastasize widely. The incidence of cutaneous metastasis from all urologic malignancies has been reported to be 0.73–1.3% with the primary most commonly being renal cell carcinoma followed by carcinoma bladder, adenocarcinoma prostate, and testicular germ cell tumor in decreasing order of frequency. Metastasis to the skin is unusual and has been predominantly reported as a late manifestation of the disease. We describe two patients with urologic malignancies who had cutaneous metastasis as their initial presenting feature.
