A Case of Verrucous Carcinoma Occurring in Patient with Diabetes Mellitus and Chronic Renal Failure


Verrucous carcinoma is a slow growing, low grade squamous cell carcinoma, which usually occurs on oropharynx, genitalia and soles. When it occurs on feet, it is known as epithelioma cuniculatum. Epithelioma cuniculatum is characterized by its histologic sinuses and cystic formations in a cuniculate(rabbit burrow-like) pattern. A 59-year-old man was consulted to our department for a well circumscribed, 5 × 5 cm sized, round, hyperkeratotic, verrucous plaque on the right great toe. He suffered from diabetes mellitus for 16 years and was managed by peritoneal dialysis three times a week due to chronic renal failure for last two years. The plaque had gradually increased in size. The biopsy specimen taken from the tumor mass showed chronic ulcerative inflammation with atypical squamous cell proliferation. We herein report a case of verrucous carcinoma occurring in a patient with diabetes melli-t tus and chronic renal failure.
