Among 5 500 seborrheic keratoses 3 were found with marked squamous cell atypia. Clinically they were seborrheic keratoses. Even though they were incompletely removed, no recurrences were observed. In contrast to some reports in the literature we regard these lesions as biologically benign, and suggest that they be treated accordingly.
