Papular: Adjective referring to one or more small solid rounded bumps rising from the skin that are each usually 0.5 cm or less in diameter (less than a half inch across).

Papules may open when scratched and become crusty and infected.

The term "papular" is derived from Latin from "papula," a pimple -- pimply.

Dermatologists (and other physicians) call any small solid circumscribed bump in the skin a papule, as opposed to a vesicle which contains fluid or a macule which is flat and even with the surrounding skin.
