Two cases of squamous cell carcinoma (SCC), both of them developed from thermal keratosis arising in areas of erythema ab igne (EAI) are reported. The lesions were located on the legs of two elderly Japanese women who had histories of chronic exposure to heat from a “kotatsu”, a type of leg‐warmer widely used in Japan. In one case, metastasis to regional lymph nodes occurred. It is emphasized that keratotic lesions arising in an area of EAI should be excised or biopsied because of the possibility of metastasizing SCC developing from them.
