Redness and itching at the base of pubic hair

The existence of pubic hair has a certain significance, especially for women, pubic hair can protect women's private parts from infection to a great extent. Redness, swelling, itching and pain at the root of pubic hair are relatively common symptoms, which are mostly caused by folliculitis. Folliculitis needs to be treated promptly. The following is a detailed introduction to the causes, clinical manifestations, examination methods, diagnosis methods and treatment methods of folliculitis.

The pathogens are mainly Staphylococci, and Staphylococcus epidermidis can sometimes be isolated. Uncleanliness, scratching and low body resistance may be the causes of this disease.

It initially appears as a red, solid papule consistent with the opening of the hair follicle, or it starts with follicular impetigo, and then rapidly develops into a papule-pustule, with the hair running through the middle and redness and inflammation all around, followed by drying and scabbing. It heals after about a week of scab falling off, but there are also cases of recurrence and no healing for many years. Some may also develop into deep infection, forming furuncles, carbuncles, etc., which generally do not leave scars. The number of rashes is large, isolated and scattered, and the patient feels mild pain. In adults, it mainly occurs in hairy areas, and in children, it is more common on the head. The rashes can sometimes merge with each other, and small bald spots may remain after healing.

3. Inspection

Direct Gram staining of pus smear can reveal pathogenic microorganisms, and stubborn cases require bacterial culture and drug sensitivity testing.

Histopathology shows acute pustular inflammation in the hair follicle area, and chronic cases may show infiltration of lymphocytes, plasma cells and histiocytes.

1. At the onset, the disease appears as a hard lump with local redness, swelling, pain and tenderness. After a few days, the source of the disease expanded, and a yellow-white pus plug appeared in the center, which then softened and ruptured, and pus was discharged. The inflammation was alleviated and gradually healed.

2. When the furuncle is large, there may be systemic symptoms such as fever, headache, fatigue, and increased white blood cell count.

3. If facial furuncle is combined with intracranial infection, the face will be severely swollen and may be accompanied by chills, high fever, headache and other cavernous sinus infection embolism.

5. Treatment

Antibiotics can be used as appropriate. 1% neomycin ointment, mupirocin ointment, fusidic acid ointment or 2% iodine tincture can be applied topically. Ultraviolet radiation can also be tried. For patients with recurrent attacks, autologous vaccine or polyvalent staphylococcal vaccine can be tried.
