A papule is an elevated solid lesion of the epidermis. It must be less than 0.5 centimeters. The color can varry. If a lot of papules come together it is called a plaque. Forewing broader than on male, pointed apically but more rounded than on male, termen slightly curved, anal margin nearly straight, black; 3 aligned translucent macules lightly scaled with white angled from mid-costa toward just basad of tornus, broadest macule in discal cell, trapezoidal (narrowest cephalad) extending distad just beyond origin of CuA.

A papule is a circumscribed, solid elevation of skin with no visible fluid, varying in area from a pinhead to 1 cm.[2][nb 1] It can be brown, purple, pink or red in color, and can cluster into a papularrash. Papules may open when scratched and become infected and crusty.[3] Larger non-blisterform elevated lesions may be termed nodules.
Papules may have differes and are sometimes associated with other features such as crusts or scales.
Causal diseases[edit]
There are many skin diseases which develop papules, such as lichen planus, a skin disease which classically forms polygonal, purple papules.[4]

Footnotes[edit]
- ^With regard to the quote '...varying in size from a pinhead to 1cm,' depending on which text is referenced, some authors state the cutoff between a papule and a plaque as 0.5cm, not 1cm, while others state an entirely different measurement. Therefore, for this article, the 1cm cutoff is used which is discussed in Andrews' Diseases of the Skin: Clinical Dermatology (see references), a work considered by some dermatologists as an authority on this subject matter. See Lack of Standardization for complete discussion.
