Keratosis pilaris decalvans non-atrophicans

A patient is described who presceted with an eruption of tiny follicular keratotic papules on the limbs and the trunk accompanied by profuse hair loss. Histologically, a diagnosis of keratosis pilaris was made. The eruption cleared spontaneously in 3 months with complete regrowth of hair. Neither atrophy nor scarring remained. This appears to be the first reported case of keratosis pilaris decalvans non-atrophicans. Profuse hair loss in areas other than scalp and independent from alopecia areata is an uncommon clinical occurrence. We describe a patient in whom it occurred on the trunk and on the limbs in apparent association with eruptive keratosis pilaris (KP).
