Abstract:
The malignant potential of burn scars has been recognized since Marjolin's classical description of cancer arising in several types of post-traumatic scars. With improved burn therapy since the last war, there has been a higher survival rate of severe burns with proportionate increase in cancer associated with burn scars. This will create increasing problems of permanent disability and compensation. The younger the patient at the time of the burn, the longer the time required for the cancer to develop. Acute cancer development in burn scars has been reported after a four-week interval. Cancer may develop from six weeks to fifty years or more. The etiology of cancer in burn scars is not known. The most important clinical finding is the fact that most of the burn cancers occur in areas which were not grafted. The most common type of cancer encountered in burn scars is squamous cell carcinoma, which forms in Marjolin ulcers. Basal cell carcinoma may develop in the most superficial of burn scars.Treatment should be directed primarily to prompt and adequate skin grafting in all deep burns in order to prevent malignant degeneration of the burn scars. Once it has developed the treatment is the same as for other malignancies which are not associated with burns. Wide surgical excision with block dissection of the regional lymph nodes when they are involved is the treatment of choice. The prognosis of burn scar cancer is poor, once the process has extended because of early and distant metastasis.
