Transformation of plantar verruca into squamous cell carcinoma.

Abstract

The authors present a case study of a long standing plantar verruca undergoing malignant transformation to a squamous cell carcinoma. This case depicts the rapid change in a plantar verruca of some 20 years' duration without any prior symptomatology. Such malignant change, while rare, can occur and any change in the color, shape, size, or sudden onset of pain in a benign lesion should constitute the consideration of possible malignancy.
