Multiple Malignant Melanomas at Different Burn Scar Areas: A Case Report

Background. Malignant changes in burn scars occasionally develop, the majority being squamous cell carcinoma. Malignant melanomas (MMs) arising in burn scars occur rarely.
Objective. To present the case of a patient with a multiple MM developed at different burn scar areas.
Methods. A case report and review of literature are given.
Results. One was a large pigmented nodular lesion with central ulceration on right flank. It was widely excised and revealed lentigo MM. After that, we took notice another small pigmented lesion on right arm. It was also reported lentigo MM.
Conclusion. This case provided a valuable lesson. Another kind of tumor may be present even if one tumor is found by pathologic observation, especially in burn scar patients. Clinicians should carefully observe burn scars, chronic ulcers, and other pigmented lesions.
