Notes on Meaning
The core meaning of papule is specific to dermatology. It is distinguished from other skin lesions primarily by its characteristics: it is small (usually less than 1 cm in diameter), solid (palpable and raised), and non-fluid-filled (it is not a blister or a pus-filled lesion). Its presence helps doctors diagnose specific diseases.
Noun
