Or total lesion count >125

Moderate Acne
20–100 comedones
15–50 inflammatory lesions
Or, total lesion count 30–125

Inflammatory lesions
- small red bumps (papules)
- pustules
- large red bumps (nodules)
- fluctuant nodules (pseudocysts)
Inflammatory acne lesions are often painful.
Usually follows rupture of the wall of a closed comedo (white head). It may also arise from normal-appearing skin.
Define Papule:
Papules: plural of papule; elevated, solid, palpable lesions that are less than 1 cm in diameter.

Define Nodule
Nodules: plural of nodule; elevated, solid, palpable lesions > 1 cm in diameter.

Define Comedo:
skin-coloured, small bumps (papules) frequently found on the forehead and chin of those with acne. A single lesion is a comedo.
Open comedones are blackheads; black because of surface pigment (melanin), rather than dirt
Closed comedones are whiteheads; the follicle is completely blocked


Comedonal acne
A pattern of acne in which most lesions are comedones. Comedonal acne most often affects the forehead and chin.
