The causes leading to the formation of impetigo

More than 80% of the pathogen Staphylococcus aureus is presented impetigo or beta-hemolytic streptococcus. Pathogen enters through cracks and abrasions of the skin, the mouth of the hair follicle.

Impetigo can occur as a primary disease or as a complication of an existing dermatoses, such as eczema, neurodermatitis (secondary impetigo). Risk factors for impetigo:

1) A tropical or subtropical climate (warm and humid conditions).
2) The summer or rainy season.
3) Slight damage the skin, insect bites, etc. (Microtrauma).
4) The poor hygienic conditions, epidemics, wars, etc.
5) The presence of impetigo in the family.

7) metabolic disorders (diabetes).
8) Impetigo may develop as a complication of head lice, scabies, chicken pox, eczema.
9) Contact dermatitis.

Manifestations of impetigo

When streptococcal impetigo appear on the skin painful red mottled Cuspal rash. Last converted into small bubbles to 0.51 cm in diameter, filled with lighter gradually mutneyuschim content and further usually painless bubbles. Eruptions scattered or congested groups are surrounded by a narrow rim of reddened skin.. They quickly opened. After the rupture of bubble-popping red sores oozing surface, they were later covered with a honey-colored crust, disappears after 57 days.
The most common rash appears on the face of the exposed parts of the body, legs, arms, but can be in other areas of the skin to the site of injury of the skin.

The rash may develop quickly or slowly.

The children most often affects the corners of the mouth strep Zayed, the wings of the nose, the skin folds of ear shells. They begin with the appearance of a bubble in the corner of the mouth with a lingering thin skin, his place quickly formed slit-like erosion, after the removal of which is detected by a red wet easily bleeding surface with a crack in the center. After 1-2 hours again Zayed crusts. The process may be accompanied by a small soreness when opening the mouth. The process is often extended to the oral mucosa. Sometimes impetigo occurs in isolation in the mouth, on the spot where the bubbles are formed quickly reveals the painful erosion, are covered by a purulent coating.
Atypical streptococcal impetigo is a kind of lichen simplex person or dry pyoderma, in which the skin (usually in children) appear pink spots of various sizes from small scales, in situ lesions were allowed to remain temporary depigmentation (skin discoloration).

A variety of cystic impetigo is a felon and a surface at which the bubble occurs on the nail fold arched around the nail on the spot burrs trauma (for example, during a manicure), needle-sticks, etc. With such a traumatizing conflict opened and formed weeping erosion in a large number of streptococci in the discharge.

When staphylococcal impetigo (folliculitis) in the mouths of sebaceous hair follicles appear blisters (pustules), reaching the value of a pea.

Folliculitis may be superficial or deep.

Superficial folliculitis is characterized by the formation of multiple small (1-2 mm, the individual may be up to 5 mm) pustules, pierced in the center surrounded by a narrow hair and a pink border. On the day of their contents 3-4 dries appear yellow crust, which after falling on the skin no trace.

With deep folliculitis of the skin are formed painful red nodules the size of 5 mm or more in diameter, sometimes with abscess in the middle. A few days later a knot dissolves or abscesses, and then opened. After healing of the nodule is often left rib.

With the combination of streptococcal and staphylococcal infection develops mixed (vulgar) impetigo, in which the contents of the vials is purulent, and crust – massive. Vulgar impetigo most often occurs on the face, trunk and limbs less. Eruptions are numerous. Without treatment, near the former eruptions or in remote areas of the skin there are new eruptions, the process often takes the common character. When removing the crusts exposed moist eroded surface. Is set to transfer to new sites of infection through the hands and clothes. Regional lymph nodes are painful on palpation and a few puffy.


The most common disease ends without consequences, but there can be complications. One of the most unpleasant complications are the complications of the kidneys (nephritis) and the heart (myocarditis).

Staphylococcal impetigo may be complicated by widespread purulent processes – abscesses and phlegmon.
