Dermatologists refer to eritism as a chronic skin pathology.This pathology is still known as pseudomycosis with a bacterial origin.It is mainly manifested in areas of large folds of the epithelium.

Features of the disease

The disease under consideration acquired its name due to the reddish glow of the diseased areas of the dermis during the luminescence study."Erytrazma" in the Greek.Yaz.Means red color.

This disease is usually fixed by dermatologists in the adult population.Men are more likely to be infected.This pathology occurs in them for a long period, with a certain feeling of discomfort, the patients are not observed.

  • sexual intercourse;
  • through personal care products;
  • when visiting the pool, bath;
  • walks barefoot( for example, on the beach).

The causative agent is noted only on the surface layer of the skin( epidermis).With the development of pathology of the nails, the hair does not affect the infection.What facilitates the penetration of bacteria inside the epidermis?These factors include:

  • friction, maceration of the dermis;

Specialists also prescribe microscopic scraping.Soskob from the affected area contains sinuous threads, like a mycelium, coccoid cells.

Disease should be differentiated from such pathologies:

  • perianal dermatitis;
