Introduction: Seborrheic keratosis (SK) has the typical pigmented dermoscopy features such as fissures and ridges, fat fingers, and cerebriform patterns. Here we describe a case where pigmented columns (PC) were visualized on SK’s dermoscopy associated with a squamous cell carcinoma (SCC). Case presentation: We report a case of a lesion whose dermoscopy showed PC. Histopathological report showed well-differentiated SCC and associated SK. Discussion: The PC was visualized in an area of dendritic melanocytes in the epidermis, correlating with the pigmented SK component of the lesion. To our knowledge, this is the first time PC is described in SK´s dermoscopy.
