We report two cases of skin lesions that clinically resemble a comedo. Both lesions demonstrated a firm black papule which was histopathologically reminiscent of a dilated hair follicle associated with an abnormality of the hair cortex. These findings are thus considered to represent a unique and peculiar variant of the dilated pore of Winer, and the term "hair cortex comedo" is therefore believed to be suitable for such lesions.
