Staphylococcal skin lesions
word "sycosis" comes from the Greek word "SyCon" - fig.This is one of the most frequent forms of chronic superficial pyoderma.
Essentially sycosis is a chronically occurring folliculitis, he immediately called golden, rarely white staphylococcus.Ill almost exclusively by men;women and children are affected very rarely.Sycosis can affect hairy areas of the skin (beard and mustache), scalp, neck, pubis, thighs and shins;but the favorite is the localization of hairy skin of the face and the front of the neck.There is a group of small, flat or pointed follicular pustules, pierced in the center of hair, painless, with little reactive redness around the circumference;after opening formed crusts, which are kept for long and after the falling away of the rack should not leave.While some pustules develop a way back, new lesions;in other cases, there are more or less long-term remission.
sycosis duration can reach several years.There were cases when a number of patients
often sycosis begins on the nasal mucosa and more rarely on the edge of the eyelids (sycotic blepharitis), and in some cases painful process is limited to ages or nasal cavity, and in other cases sycosis spreads to the skin first upper lip, and thenand other hairy areas of the face, often striking, except for the upper lip, the chin, cheeks and neck.It must be borne in mind that the sycotic blepharitis often develops in chronic conjunctivitis, and sycosis nasal cavity - have chronic rhinitis.Often eczematization sycosis is complicated, often in the future the phenomenon itself sycosis effaced before clinical eczema.
Etiology and pathogenesis
etiological factor is the staph, but the disease of the presence of these microorganisms is not enough, because, according to modern concepts, Sycosis develops only in the case when these are predisposing factors, primarily on the part ofmicroorganism.Under these conditions, always saprofitiruyuschie on human skin, and it is in place to start the process sycotic (in hair craters), staphylococci are pathogenic and cause disease.These predisposing and then supporting chronic sycosis factors may be different:. Disorders of the nervous system, internal organs and endocrine, etc. It should be borne in mind that there are often suffering from sycosis hypogonadal.A number of patients sycosis able to communicate clearly the origin and subsequent recurrences of the disease with severe nervous and mental experiences.Patients sycosis usually increased skin sensitivity to staphylococcus and their products, t. E. Specific giperergii stated condition that must be considered when assigning treatment.
Histologically first picture is the same as when staphylococcal folliculitis, later purulent process captures the upper part of the follicle up to the confluence of the sebaceous gland duct.Perifollicular inflammatory infiltrate consisting of lymphocytes, plasma cells, polynuclear leucocytes and in some cases the giant cells.At the same time marked swelling and enlargement of the lymph cracks, swelling of the collagen fibers.The papillae and the epidermis near the lesion and swollen, styloid in bed a lot of mitosis.At the border area edematous and normal marked acanthosis.Throughout the lesion revealed a significant number of pathogens -stafilokokkov.
the most part, the diagnosis is not difficult.From parasitic or trihofitiynogo ordinary sycosis sycosis different surface nature of the disease process, the absence of sharply defined and protruding above the normal level of the skin sites.Only in rare nodular form of non-parasitic sycosis are formed, as the name itself indicates, the individual components, but they are much smaller quantities and have honeycombed characteristic deep trihofitii.The flow of non-parasitic sycosis chronic, but every single eruptive element of it there for a short time;when the parasitic sycosis during acute illness, with relapse never remains immune, while at staphylococcal sycosis, on the contrary, for a long time is a tendency to relapse of the disease.In difficult cases the diagnosis is made for bakterioekopicheekoe study of hair and pus on the elements of Trichophyton, and crops;auxiliary diagnostic value may have a skin test.
- Sycosis ordinary
- Multiple abscesses in children (psevdofurunkulez Finger)
- Pustular skin diseases
Observehygiene skin care measures face and other hairy areas of the skin.Essentially sycosis prophylaxis is not different from that in other forms of pyoderma.Since the Sycosis often develops in patients suffering from seborrhea, treatment of the latter part of the set of preventive measures sycosis.Solving all kinds of diseases and disorders of the internal organs (especially on the part of the gastrointestinal tract), endocrine and nervous systems are also of paramount preventive value.Many preventive value is treatment of conjunctivitis and rhinitis, as well as other forms of pyoderma, if present in the patient, for it is not so rare Sycosis develops from "accidental" folliculitis or boils.
