Favus Impetiginous

Favus or scab is a chronic mycosis caused by the Malassezia fungus and is characterized by lesions of the skin and nail beds of the toes and fingers. Favus gets its name from the Latin "faveus", meaning "skin of a cow".

Favus is one of the most common dermatophytes and primarily affects the skin of the feet and palms, as well as the fingernails. Favus lesions may be accompanied by itching, burning and tingling, especially at night.

The occurrence of favus is associated with a violation of the skin microflora. A weakened immune system allows Malassezia bacteria to exhibit pathogenic properties and cause the development of disease. In addition, predisposing factors to the development of favus are a lack of vitamins and minerals, improper skin care, wearing tight shoes, and metabolic disorders.

Treatment of favus should be comprehensive and include the use of antifungal drugs such as ketoconazole, itraconazole or terbinafine, external preparations in the form of creams and ointments. An important condition for treatment is compliance with hygiene rules and regular change of linen.
