Regressive melanoma with lichenoid tissue reaction may be clinically and histopathologically challenging. A 73-year-old male visited our clinic for a general skin checkup. We noticed a red papule on the right side of his back. On dermatoscopy, scattered grayish dots were observed. The differential diagnosis included lichenoid keratosis and melanoma. Histopathological examination of the excised lesion showed a regressive melanoma with a histopathological pattern of lichenoid keratosis.
