Epitheliomatous degeneration of the scar of a burn is well known. When this change occurs the age of the scar and not the age of the patient is the important factor. According to Pack and Livingston,1 an average interval of nineteen years elapses between the inception of the burn and the development of the cancer. Most authors agree that the tumor growth is slower than that seen in cancer of the normal skin. When the underlying muscle and connective tissue is invaded and an adequate supply of blood is present, the growth is usually rapid. The type of tumor invariably found is a squamous cell epithelioma.2
The case to be reported was considered interesting because two distinct epitheliomatous ulcers occurred in a dense cicatrix sixteen years after an extensive burn.
