Symptoms of florid furunculosis include well-defined punctate plaques covered with furfuraceous scales.
It is caused by the invasion of the stratum corneum of the skin by the bacterium Malassezia, while high temperature and humidity, malnutrition and other factors are the predisposing factors. Usually, the lesions of pityriasis versicolor start as pore-centered, well-bordered dotted rash, which may be brown or white. As the disease progresses, the lesions will gradually increase to the size of a fingernail cap, can be fused with each other to form large irregular patches, and the surface is covered with furfuraceous scales.
In addition, patients with pityriasis versicolor generally have no conscious symptoms, occasionally mild itching, and the disease is mild in winter and severe in summer. Furfury is not contagious and will not jeopardize life and health, but the disease is difficult to cure and has a high recurrence rate, so attention should be paid to it.
It is recommended to adjust the mentality of people with pityriasis versicolor, actively consult and cooperate with doctors for treatment, strengthen daily skin care, keep the affected area clean and dry, and do not scratch or wash the skin.
