Pustular acne

Introduction Pustular acne is a type of acne. Puss is the main expression, pustules are the size of grain to mung bean, pustules are formed at the tip of follicular pustules and papules, and the pus is thicker after the break, leaving a shallow scar. Pustular acne is a relatively serious type of acne, the main clinical manifestations of inflammatory papules and pustules. Pustular acne begins with punctate erythema or small papules that develop rapidly into peas, miliary, or blisters. If left untreated, it will become a pustule.

Cause

Pustular acne production has a certain relationship with poor diet, negative emotions, irregular work, and the proliferation of acne bacteria, but the main reason is due to endocrine disorders, decreased skin resistance, and long-term accumulation of toxins.

Immunology

In the humoral immunity of patients, serum IgG levels increase and increase with the severity of the disease. Corynebacterium acne produces antibodies in patients, and circulating antibodies reach local involvement in the pathogenesis of early inflammation.

Trace element

The low zinc in patients with pustular acne may affect the utilization of vitamin A, promote the keratinization of the hair follicle sebaceous glands, and the low copper will weaken the body's resistance to bacterial infection. In short, the trace elements zinc, copper and iron in patients with acne are low, manganese liter High can cause fat metabolism and sex hormone secretion in the body to be affected, and the skin resistance is low, which may have a certain relationship with the incidence of acne.

Genetic

Genetics is also an important factor in the development of pustular acne.

Pustular acne: mainly abscesses, pustules are grain-to-mung bean size, pustules are formed at the tip of follicular pustules and papules, and the pus is thicker after the break, leaving a shallow scar.

Differential diagnosis

Differential diagnosis of pustule type acne:

1. Point acne: Blackhead acne is the main damage of acne. It is a cheese-like semi-solid embedded in the hair follicle of the hair follicle. It is black at the outer end of the hair follicle. If it is squeezed, the head is black and the body is visible. A yellow-white translucent lipid plug is discharged.

2. Papular acne: The skin lesions are mainly inflammatory small papules, and the hard small papules from millet to pea are light red to deep red. The center of the papule may have a blackhead acne or a sebaceous plug that does not become black at the top.

3. Nodular acne: When the inflamed area is deep, pustular acne can develop into wall thick nodules of varying sizes, showing a reddish or purplish red color. Some are deeper and have a prominent bulge in a hemispherical or conical shape. They can be long-term or gradually absorbed, and some purulent ulcers form a significant scar.

4. Atrophic acne: Papular or pustular lesions destroy the gland, causing a pit-like atrophic scar. Broken pustules or naturally absorbed papules and pustules can cause fibrosis and atrophy.

5. Cystic acne: the formation of sebaceous cysts of varying sizes, often secondary to purulent infection, often with bloody jelly-like pus after rupture, and inflammation is often not heavy, after the formation of sinus and sputum.

6. Polymeric acne: It is the most serious type of damage. The skin lesions are polymorphous. There are many acne, papules, pustules, abscesses, cysts and sinus, scars and keloid clusters.

7. Helmintic acne: The damage is from cyan to fuchsia-sized cyan or purplish papules, pustules or nodules, soft and supple, and contains pus.
