Verrucous carcinoma on melanoma graft after melanoma surgery: Case Report

Abstract

Cutaneous verrucous carcinoma is a rare and well-differentiated variant of squamous cell carcinoma, which is characterized by slow growth and low metastatic potential, but which can be locally aggressive and whose recurrence is not uncommon. Tumors usually develop in older adults, usually patients 50 to 70 years of age and predominantly in Caucasian men. It can arise in chronic inflammatory conditions. It manifests as an exophytic tumor with a warty surface and the plantar shape stands out for its slow growth and low metastatic potential; however, it is locally aggressive. We present the case of a 69-year-old female patient, with a history of melanoma in the left heel reconstructed with a graft 10 years ago, who presented with a yellowish, ill-defined, 2-month-old, asymptomatic warty plaque, for which a skin biopsy was performed that reported verrucous carcinoma.
