Keratosis Pilaris/Lichen Spinulosus

Definition

Keratotic spikes that emerge from dilated ostia of infundibula and are equidistant from one another. The term keratosis pilaris refers to the phenomenon when it presents itself without any distinct arrangement of individual lesions, whereas the designation lichen spinulosus is applied to the same lesions when they are arranged in a circle.
