summary

Tinea versicolor, commonly known as sweat spots, is a superficial fungal disease caused by Malassezia furfur infection of the cuticle of the epidermis. Tinea versicolor is more likely to appear in tropical and temperate areas with higher humidity, and it is also more common in young people, especially young men; What reason is tinea versicolor caused? Next, I'd like to share my views with you.

What reason is tinea versicolor caused?

First, the pathogenic bacteria is a kind of lipophilic yeast, called Malassezia. This kind of fungi is saprophytic bacteria of normal skin. Only in some special circumstances, such as high temperature, high tide, local fat and sweat, poor sanitary conditions, etc., the parasitic density of Pityrosporum is increased, and the saprophytic yeast is transformed into mycelial type.

Second, the bacteria only invade the superficial stratum corneum and do not cause the inflammatory reaction of dermis. The disease is common in tropical and temperate regions with high relative humidity. Young people, especially young men, are more prone to pityriasis variegata due to more activities and sweating.

Third: pityriasis versicolor is also more common in people who use corticosteroids, because the epidermal cell replacement cycle of such people is prolonged, which is conducive to the growth of fungi. If the hormone is stopped, pityriasis versicolor will improve. In addition, physical weakness, malnutrition, diabetes and pregnancy can induce the disease.

matters needing attention

(1) Develop good personal hygiene habits, wash frequently and change frequently（ 2) Reasonable nutrition, because malnutrition can induce the disease, for patients receiving corticosteroid therapy should pay attention to observe and prevent the disease.
