Erythrasma is a skin infection caused by the bacterium Corynebacterium minutissimum that leads to the appearance of spots on the skin that can peel off. Erythrasma happens more frequently in adults, especially in obese and diabetic patients, since the bacteria is usually found in which there is friction of the skin, such as in the folds, that is, the armpit and under the breasts, for example.
This skin disease can be easily diagnosed using the Wood Lamp, which is a diagnostic method in which the lesions acquire a specific color when exposed to ultraviolet light. In the case of erythrasma, the lesion acquires a coral-red luster and can thus be differentiated from other lesions. The diagnosis can also be made through the scraping of the lesion, which is sent to the laboratory for identification of the microorganism, but it is a more time-consuming method of diagnosis.
How the treatment is done
The treatment for erythrasma is done according to the dermatologist's guidance and is usually done with the use of antibiotics, such as Erythromycin or Tetracycline, for 10 days or according to the medical recommendation. In addition, the use of specific ointments for erythrasma, such as erythromycin cream, may be recommended. If the presence of fungi is identified in the lesion, the use of antifungal creams or ointments may also be recommended by the doctor.
During treatment it is advised that the person uses antibacterial soaps to wash the affected area, with the use of those containing chlorhexidine being more recommended.
Main symptoms
Erythrasma has as its main symptom the presence of pink or dark and irregular spots that can flake and lead to the appearance of cracks in the skin. In addition, there may be slight flaking.
Lesions tend to appear more frequently in regions where there is skin-to-skin contact, such as under the breast, armpit, between the feet, groin and intimate area. The large production of sweat or inadequate hygiene of these regions can also favor the appearance of lesions characteristic of erythrasma.
