Known as sputum, multiple and recurrent episodes of sputum called rickets, severe cases may have lymphadenopathy, fever, headache, and even cause sepsis or sepsis; if squeezed in the nose, lips and edema, can make Pathogens enter the skull through the blood, causing suppurative thrombophlebitis or brain abscess, which can lead to death.
Symptom
Symptoms of folliculitis Symptoms Abnormalities of the outer side of the eyebrows are sparse and fine eyebrows become white hemorrhagic papules itching papules purulent secretions blush mild pain cosmetics hair damage pustules
The rash starts at the mouth of the hair follicle, and there is a red hair follicle with a itchiness from the tip of the needle to the size of the mung bean. The top of the papule forms a yellow-white small pus, surrounded by an inflammatory blush, and the center has hair follicles penetrating, and the papules appear more and scattered. Do not blend with each other, have mild pain, itching is obvious, generally no systemic symptoms, after a few days, the pus head rupture, discharge a small amount of pus gradually, such as repeated attacks, prolonged for several weeks, good to become chronic folliculitis, good hair In the hairy parts, scalp, perineum, ankle, perianal and extremities, the rash is easily secondary to seborrheic dermatitis, neurodermatitis, pruritus and other diseases.
Initially an inflammatory small papule consistent with hair follicles, surrounded by redness, rapidly becoming pustules, often with hair running through the center, pustules such as miliary size, not fused, thin blister wall, a small amount of purulent secretion after breaking Consciously itching and slight pain, dry and crusted after a few days, no scars, more common in adults, occur in the scalp, the main parts, also found in the buttocks, etc., local lymph nodes can be swollen, stubborn nature, tend to relapse, often Prolonged for a long time.
Examine
Folliculitis examination
Folliculitis check:
Pseudo-smear Gram staining can be used to detect pathogenic microorganisms, and stubborn cases require bacterial culture and drug sensitivity experiments.
Histopathology is acute pustular inflammation in the hair follicle area, and lymphocytes, plasma cells, and histiocytic cells may infiltrate in chronic cases.
Bacterial folliculitis pus directly smear Gram stain can be found in pathogenic microorganisms, stubborn cases need to be used for bacterial culture and drug sensitivity experiments. Bacterial folliculitis histopathology is acute pustular inflammation in the hair follicle area, and lymphocytes, plasma cells and histiocytic cells may infiltrate in chronic cases.
Diagnosis
Diagnosis and differentiation of folliculitis
diagnosis
According to the predilection site, the lesion is an inflammatory papule with consistent hair follicles, and the smear microscopy or bacterial culture is helpful for diagnosis and identification of pathogenic microorganisms.
Diagnose based on:
1. Onset is an induration, local redness, swelling, pain and tenderness. A few days later, the source of the disease expanded, and a yellow-white pus was found in the center, which then softened, ulcerated, and drained, and the inflammation was relieved.
2. When the edema is large, there may be systemic symptoms such as fever, headache and fatigue, and the number of white blood cells is increased.
3. Facial edema, such as intracranial infection, facial swelling is serious, can be accompanied by chills, high fever, headache and other cavernous sinus infection embolism.
TCM pathogenesis and dialectic:
1. The pathogenesis of Chinese medicine believes that the disease is moist and hot, externally exposed to heat, stagnation on the skin, or the factors are weak, the phlegm is not solid, and the heat is caused by heat.
2. Dialectical analysis of damp heat type: body surface scattered in reddish papules, small pustules, consciously itchy, slightly painful, reddish tongue, thin white fur, pulse string, syndrome differentiation is wet and heat intrinsic, exogenous poisonous evil, qi and blood deficiency Type: The body is weak, the complexion is sallow, the food is poor, the tongue is light, the fur is thin, the pulse is fine or slow, and the syndrome is a lack of qi and yin.
Differential diagnosis
1. Hair follicle impetigo, which occurs mostly in the area of the mane, with more extremities on the extremities, larger pustules, more secretions, and easier to thicken.
2. The folliculitis drug eruption is mostly caused by iodine, amalgam, and bromine. There is no certain predilection site, and there is a history of taking the drug. After a short period of time, it can be cured after stopping the drug.
3. Hair keratinization: usually related to heredity, the skin around the hair is red and swollen, the hair is broken, and the hair follicle is blocked by the stratum corneum.
