A 69-year-old man, who got burned on the back of his head by falling down into an irori (Japanese hearth) at the age of 2, was referred to our clinic for the evaluation of bleeding on the burn scar. Physical examination revealed a 20×10 mm black ulcerated plaque and a discrete 3 mm black freckle at the center of the extensive burn scar on his parieto-occipital region. A biopsy from the larger plaque revealed them to be a basal cell carcinoma (BCC). Burn scar is a well-known pre-cancerous lesion. In a 24-year- period from 1985 to 2008, we experienced 31 cancers in 30 patients consisting of 28 SCCs and 1 each of BCC, malignant fibrous histiocytoma (MFH), and fibrosarcoma. SCC and MFH developed in one patient. Our review of the Japanese literature uncovered 14 BCC cases in 27 years. In the English literature, 412 cancers on burn scar including 293 SCCs and 48 BCCs were reported from 1923 to 2004. BCC developed on burn scar is relatively rare compared to squamous cell carcinoma (SCC), a most common cancer on burn scar.
