The pathogens are mostly Staphylococcus aureus, sometimes Staphylococcus aureus, often caused by insect bites, injuries, and scratches. There are pustules under the corners of the hair follicle opening. There are a large number of neutrophils, residual keratin and necrotic epithelial cells in the pustules. Epidermal cells edema around the pustule, connective tissue edema around the upper part of the hair follicle, vasodilatation, and more neutrophil infiltration around it. basic knowledge The proportion of illness: 0.06% Susceptible people: no special people Mode of infection: non-infectious Complications: Asthma Eczema

Causes of eosinophilic pustular folliculitis

Cause:

In the early stage, the hair root outer sheath cells, intercellular edema, eosinophils, neutrophils and monocytes infiltrated, and abscesses formed in the hair follicles. The abscess contained a large amount of the above cells.

Examination of eosinophilic pustular folliculitis

The white blood cells were moderately increased, and the eosinophils were significantly increased to 0.46×10 ⁹ /L, which generally fluctuated between (0.02 and 0.26)×10 ⁹ /L. No pathogenic bacteria were found in the bacterial culture.

Early in the hair root outer sheath cells, intercellular edema, eosinophils, neutrophils and monocytes infiltration, abscess formation in the hair follicles, abscess contains a lot of these cells, hair follicles and blood vessels around the eosinophils, The granulocytes and monocytes infiltrate and the hair is intact.

Diagnosis and identification of eosinophilic pustular folliculitis

According to clinical manifestations, laboratory tests and pathological sections, the diagnosis of this disease is not difficult.

1. Impetigo: It is a highly contagious, bacterial skin infection that occurs in younger children, especially babies. The disease mainly affects the child's mouth and nose skin and the baby's diaper area, and sometimes it can appear in other parts of the body.
