Verrucous carcinoma arising in the setting of postnephrectomy sinus

Marjolin′s ulcers are malignancies that arise in chronic venous ulcers, scars, burns, long-standing wounds or sinuses. The most common type of carcinoma arising in the Marjolin′s ulcer is squamous cell carcinoma (SCC), followed by basal cell carcinoma. Verrucous SCC (VSCC) comprises about 3% of all SCCs. It is most commonly diagnosed in the oral cavity, and the incidence is approximately one in a million/year. To the best of our knowledge, malignancy arising in a postnephrectomy sinus has never been described before. We herein report a case of VSCC in a sinus developed after nephrectomy done for renal stones.
