Follicular granular parakeratosis.
An 83-year-old patient presented herself with a ten-year history of keratotic papules on her trunk. A biopsy of this process revealed granular parakeratosis confined to the infundibulum of a follicle. Exclusive follicular involvement in granular parakeratosis has not been previously described.
