Gigantic malignant melanoma in a thermal burn scar.
Carcinoma developing in burn scars is overwhelmingly of the squamous cell type; in fact, almost 2% of all squamous cell carcinomas develop in old burn scars. We report a case of malignant melanoma that developed in a burn scar and review eight other reported cases of malignant melanoma that developed similarly. We also compare the group having malignant melanomas in burn scars with those having the more common type of squamous cell carcinoma in burn scars.
