ABSTRACT
BACKGROUND:
Marjolin's ulcer forms part of a group of neoplasms that originate in a burn scar, a phenomenon associated with superficial tissue trauma. The frequency of Marjolin's ulcer is low and represents between 2 and 5% of all squamous cell carcinomas of the skin. This condition is found three times more frequently in men than in women and is thought to be more aggressive than conventional squamous cell carcinoma of the skin. CLINICAL CASES We present two cases of squamous cell carcinoma that originated on a burn scar. 41 year old woman with gasoline burn on the left foot, 3 months old, in whom an exofitic ulcerated lesion on the right calcaneum region has evolved since she was 32 years old. Left transtibial amputation was decided. Another woman who started its suffering 9 years after a thorax burn with a progressive fungus lesion on the scar area. For its size and as it was a high degree neoplasia, surgical resection and radiotherapy to the zone of the primary with 50 Gy in 25 fractions was decided.CONCLUSIONS:
Marjolin's ulcer usually occurs in old burn sites that were not skin grafted and were left to heal secondarily. Although it is believed that there is a latency period of 25-40 years after burn injury before the occurrence of malignancy, this may occur in a period as short as 3 months. Recurrence after radical surgery is 14.7%. Nonetheless, because of the aggressive behavior of this type of cancer, appropriate radical treatment allows an adequate control of the disease. Early grafting of the burn site can prevent the formation a malignant neoplasm. This condition should be suspected in a non-healing chronic ulcer on a burn scar.
