Erythematous dandruff(Latinerythrasma ) is caused by bacteria - corynebacterium minutissimum, which belong to the natural flora of humans.

The skin changes in the case of erythematous dandruff are mainly located in the skin folds, both natural ones, as well as those resulting from overweight or obesity. The first symptom of erythematous dandruff is the appearance of the so-called primary bloom. It is a pink, yellowish or dark brown erythema spot peeling on the surface, most often located in the groin area, where the testicles or labia meet the thighs, between the buttocks, in the navel, in women under the breasts, as well as in the interdigital spaces of the feet. Untreated lesions tend to expand and occupy larger and larger areas of the body.

The presence of coryneform bacteria can also be found after collecting scrapings and staining them with methylene blue.
