A 70－year－old man presented with a 4－year history of erosion on the right dorsum of his foot, where he got a burn, for which he underwent conservative treatment at the age of 17 years. Squamous cell carcinomas (SCCs) developed twice on the burn scar when he was 51 and 66 years old, and both were surgically removed. One month after the operation for the second SCC, a keratotic nodule developed on the right inner ankle, which was also part of the burn scar. We surgically resected the tumor and diagnosed it pathologically as malignant melanoma in situ. Approximately 2 years later, an ulcer developed on his right inner ankle. The tumor was resected and diagnosed as malignant melanoma. As multiple different skin cancers may develop on burn scars over time, careful and long－term follow－up is essential for early diagnosis and treatment.[Skin Cancer (Japan) 2020 ; 35 : 52－57]
