What does papule mean?
A papule is a small, solid, raised spot that develops on the skin or mucous membrane, often as part of a larger eruption. Unlike a pustule, it does not contain visible pus, although it may become inflamed or itchy. Papules can occur in many different skin conditions, so the term is mainly used in clinical and dermatological descriptions rather than ordinary conversation. In general speech, people are more likely to say “spot,” “bump,” or “pimple,” but these words do not make the same precise medical distinction. Knowing the term can help readers interpret descriptions of rashes, eruptions, and other skin findings more accurately. The word is pronounced “pap-yool” and comes from Latin.
