A papule is a circumscribed, solid elevation of skin with no visible fluid, varying in size from a pinhead to 1 cm.[1][nb 1] They can be brown, purple, pink or red in colour, and can cluster into a papular rash. The papules may open when scratched and become infected and crusty.[2]

Papules may have different shapes and are sometimes associated with other features such as crusts or scales.
