Allen refers briefly to these growths as examples of "isolated Darier's disease" in his textbook.2 Montgomery mentions a lesion which appeared to be a senile keratosis of the forehead of 15 years' duration.3 Histologically it imitates the microscopic picture of keratosis follicularis. However, it was considered to be a senile keratosis exhibiting a benign type of dyskeratosis. A search throughout the dermatologic literature did not uncover a report of localized tumors resembling keratosis follicularis microscopically. I have had an opportunity to study two such lesions, clinically and microscopically. The clinical descriptions and
