[The Marjolin's ulcer, destiny of a unstable scar. About 54 cases of burn's sequelae].

Through a study of 54 cases of malignant transformation on burn's scar, collected during a period of 8 years, the authors underline the particularities of this tumor, reported at the literature such as the preponderance of spinocellular carcinoma as histological type, the high rate of lymphatic metastasis and recurrence, and also the poor prognosis. In addition, the authors underline the non-rare character of this affection, whose incidence is correlated to the level of medication; it's occurring in younger patients, and its short delay of transformation. The treatment is based on prevention by a correct management of the initial burns, the cure of any instable scar, and a regular surveillance. The biopsy should be realised in case of suspicion of degeneration. The radical treatment must be initially aggressive, consisting on large excision associated eventually to radiotherapy. This treatment must be integrated in an elaborating therapeutic strategy, taking on consideration the evolutive potentiality of these tumors in order to improve chances of recovery and survival.
