Staphylococcal piloderma. Furuncle

Furunculosis is an acute purulent-necrotic inflammation of the hair follicle and perifollicular connective tissue. The furuncle refers to the deep form of staphyloderma. The primary eruptive element of the furuncle is an inflammatory node that forms around the hair follicle infected with staphylococci.

The onset of the disease is associated with the formation of an inflammatory purulent infiltrate around the hair sac, which in the early stages can be small (like folliculitis), however, the process quickly captures the entire depth of the hair follicle surrounding the connective tissue and adjacent sebaceous gland and is an inflammatory, stagnant-hyperemic node , conically rising above the surface of the skin.

With the localization of the boil in the area of ​​the face, extensive swelling is noted around the infiltrate. After 3-4 days, a fluctuation begins to be detected in the center of the infiltrate, a purulent fistula is formed around the hair, at the opening of which a small amount of thick pus is released, a small ulcer is formed. At the bottom of this ulcer, a necrotic stem of a greenish color is detected. After another 2-3 days, the necrotic core is rejected. In place of the rejected necrotic core, a deep crater-like ulcer is formed, which is filled with granulations, an inverted scar is gradually formed.

Particular attention should be given to patients in whom the boil is located in the area of ​​the lips, on the nose, in the nasolabial triangle and in the area of ​​the external auditory canal.
Mimic facial movements, trauma to boils during shaving or attempting to squeeze them out can lead to serious complications (thrombophlebitis of the face veins).

Anatomical features of venous outflow on the face, the presence of anastomoses with cavernous sinus of the brain can lead to more serious complications - the spread of staphylococcal infection and the development of meningitis, meningoencephalitis, septicopyemia and sepsis with the formation of multiple abscesses in various organs and tissues.

Furunculosis. This is the presence of multiple boils on the skin or the sequential recurrence of boils. There are acute furunculosis, in which many boils are simultaneously present on the skin, and chronic furunculosis, when boils (single or multiple) recur sequentially at short intervals for months and even years. By prevalence, localized (limited) furunculosis and widespread (disseminated) are distinguished.

Acute furunculosis develops with short-term exposure to exogenous and, less commonly, endogenous predisposing factors, while chronic furunculosis develops with the prolonged presence of endogenous predisposing factors.

Localized furunculosis (acute and chronic) develops as a result of the introduction of staphylococci into several adjacent follicles.

Staphylococcal piloderma. Furuncle

  1. Staphylococcal pyoderma. Carbuncle, or carbohydrate. Hydradonite
    Carbuncle is a very severe and deep form of staphyloderma, which is a purulent-necrotic inflammation of the deep layers of the dermis and hypodermis, involving many hair follicles in the process. It is caused most often by the most pathogenic Staphylococcus aureus. In the pathogenesis of carbuncle development, weakening of the body's defenses, diabetes mellitus, immunosuppressive drugs are of great importance
  2. Furuncle
    A boil, or BOIL, is an infectious, painful subcutaneous inflammation that results in an abscess with lots of pus. A boil occurs around a hair sac. See the article ABCESS, with the addition that some situation poisons a person’s life, causing him great anger, anxiety and fear. These negative emotions are so intense that they prevent the body from getting rid of
  3. FURUNCUL and CARBUNCUL
    A boil is an acute painful perifocal inflammation of the hair follicle, most often occurring on the face, neck, chest and buttocks. Recurrent infection turns into a disease of furunculosis. Carbuncle is a conglomerate of furuncles resulting from subcutaneous infection, leading to purulent-necrotic inflammation of the deep layers of the skin, often with local rejection of necrotic
  4. Furuncle nose
    Boil - purulent-necrotic inflammation of the hair follicle, adjacent sebaceous gland and fiber. The wide involvement of surrounding tissues in the inflammatory process is a qualitative difference between the boil and the one close to it in etiology and pathogenesis of ostiofolliculitis. The ability to unlimited spread of inflammation, with features of the venous system of the face and the likelihood of rapid development
  5. Boils
    The clinical picture of the boils of the external auditory canal The furuncle of the external auditory canal is a limited inflammation in the cartilaginous part of the external auditory canal. With minor skin damage, the infection enters the hair sacs and sebaceous glands, where inflammation begins. There is a sharp pain in the ear, often giving to the teeth, worse when chewing, sharp pain with
  6. Furuncle nose
    A boil of the nose is an acute inflammation of the hair bag or sebaceous gland. Et and about l about d and I. Of primary importance is a local decrease in the resistance of the skin and the whole organism to staphylococcal and streptococcal infections. Under these conditions, the microflora, getting into the hair bags and sebaceous glands of the skin, more often the lower third of the nose and its vestibule (often introduced by hands), usually causes acute purulent
  7. Boil and furunculosis
    Acute staphylococcal purulent-necrotic inflammation of the hairs. follicle and surrounding junction. tissue. Etiology. The causative agent is golden, less often white staphylococcus. Pathogenesis. It can form on unchanged skin, be a complication of the existing surface. or deep staphyloderma. The virulence and pathogenicity of the pathogen strain, exogenous and endogenous predisposal affect the occurrence.
  8. Boil of the external auditory meatus
    Furuncle (otitis externa circumscripta) - acute purulent inflammation of the hair sac, sebaceous gland with limited inflammation of the skin and subcutaneous tissue of the membrano-cartilaginous part of the external auditory canal. Et and about l about d and I. The disease occurs as a result of infection, more often staphylococci, entering the sebaceous and hair sacs when irritated skin is irritated by manipulations in the ear.
  9. Auditory meatus furuncle
    Cause Microtrauma of the skin of the external auditory canal when picking in the ears, hypothermia, impaired carbohydrate metabolism, hypovitaminosis. Symptoms Strong shooting pain in the ear, if you pull off the earlobe or press on the tragus - the pain in the ear increases. Increased pain also occurs with chewing and yawning. The skin of the external auditory meatus is reddened, swollen. The disease may be accompanied.
  10. Furuncle of the nose, features of the clinic, therapeutic tactics
    A boil of the nose is most often the result of scratching in the nose with infection in the sebaceous and hair sacs located on the threshold of the nose; less commonly, one of the manifestations of general furunculosis. Clinic. Hyperemia of the skin, tension and soreness of the tissues appear on the tip or on the wings of the nose. Inflammatory phenomena in the form of redness and swelling often capture the neighboring parts of the face. At

    {foto26} Treatment outcome: Clinical criteria for improving the patient's condition: 1. Normalization of temperature. 2. Normalization of laboratory parameters. 3. Improving the clinical symptoms of the disease (pain, difficulty breathing, purulent discharge from
  12. FURUNCULOSIS
    Furunculosis is an acute purulent-necrotic inflammation of the hair sac, sebaceous gland and surrounding loose fiber, usually caused by staphylococci and accompanied by the formation of boils. Scouring and other skin lesions, polyhypovitaminosis and metabolic disorders, as well as seborrhea and acne, contribute to furunculosis. The cause of furunculosis and individual boils may be
  13. Acute otitis externa (diffuse, limited)
    Acute external limited otitis media (ear boil) The boil of the external auditory canal is found only in the cartilaginous section, since hair and sebaceous glands are absent in the skin of the bony section. Etiology - the introduction most often of staphylococcal infection into the glands and hair sacs due to picking in the ears with a fingernail or various objects, especially with suppuration. Ear boil can be
  14. External otitis
    Among inflammatory diseases of the outer ear, there are limited and diffuse external otitis media. In the first case, it is a boil, and in the second, a large group of inflammatory diseases of bacterial, fungal, viral origin, or dermatitis, characterized by severe allergic reactions. Diffuse otitis media includes external purulent otitis media, otomycosis, eczema, dermatitis,
  15. OTITIS
    Classification Depending on the location of the infection, otitis media is divided into external and secondary. EXTERNAL OTITIS External otitis is an infectious process in the external auditory canal, which can be localized (the boil of the external auditory canal) or diffuse when the entire canal is involved (generalized or diffuse external otitis media). In addition, a separate clinical form is isolated.
  16. The main groups of skin diseases
    Infectious and parasitic skin diseases. Although the skin is a powerful protective organ, its barrier function can be disrupted by microorganisms and parasites (table. 37.7). With unstable immunity, banal skin infections, manifested by abscesses, carbuncles or boils, can be life-threatening. Table 37.6 1. Infectious and parasitic diseases 2. Acute and chronic dermatitis
  17. Staphylococcal pyoderma
    The pathological process develops in the deep layers of the skin, mainly in the area of ​​hair follicles, in the sebaceous and sweat glands. The following varieties of staphylococcal lesions are distinguished: ostiofolliculitis, vulgar sycosis, folliculitis, boil, carbuncle, hydradenitis, epidemic pemphigus of newborns. Osteofolliculitis. The pustule is located at the mouth of the hair follicle, in the center
  18. Primary cavity elements
    Bubble (vesicula) is formed as a result of spongiosis or vacuole and ballooning degeneration, comes from the epidermis, up to 5 mm in diameter. At autopsy, erosion is formed, which becomes crusty, leaves pigmentation behind itself or disappears without a trace (eczema, simple vesicle lichen, herpes zoster, etc.). Bubble (bulla) - the size is more than 5 mm in diameter, hemispherical
