Mostly uncharacteristic (usually "steroidally" pretreated), 0.5-5.0 cm large, red but also reddish-brown, scaly, mostly itchy, possibly also weeping, only moderately elevated, borderline plaques.

Diagnostically groundbreaking are scattered 0.2-0.4 cm red follicular papules or papulopustules.

In individual patients, however, highly red, flat-exposed plaques, usually interspersed with follicular pustules, may also be present.

Hair can be easily extracted from these plaques. These show a cuff of hyphae and spores in the native preparation.

Frequently, tinea lesions can also be detected on other skin areas (e.g. tinea corporis et faciei).
