Malignant melanoma on a thermal burn scar

Chronic burn scars often cause various skin malignancies at rates of up to 2%. These lesions are usually squamous cell carcinomas, but rarely, malignant melanoma is reported. We report a 67-year-old male with a malignant melanoma on a burn scar with regional metastasis. This patient presented an ulcerative lesion only in 2 weeks. After histopathological diagnosis, we performed only palliative surgery on patient's demand, and followed up the subsequent deterioration course. Our case reemphasizes the need for rapid diagnosis and treatment when suspect lesions are present on chronic burn scar. Also, physician should be in mind and inform the patient about malignant melanoma and its aggressive course.
