Exuberant verrucous carcinoma arising from a burn scar

ABSTRACT

Verrucous carcinoma (VC) is an unusual, well-differentiated, and low-grade type of squamous cell carcinoma, characterized by slow growth, low metastatic spread, local invasion, and little dysplasia. It occurs predominantly on the genitals, in the oropharynx, or in the palmoplantar region, being less frequent at other sites; however, it can occur on any part of the body. Many factors have been associated with its pathogenesis, including the presence of previous skin lesions, such as varicose, decubitus, traumatic, or neuropathic plantar ulcers. VC arising from a burn scar is rare. We report the case of a patient who developed exuberant VC on his knee many years after having burn injuries at that site
