FUNGUS DISEASES OF SKIN

From Big Medical Encyclopedia

FUNGUS DISEASES OF SKIN (synonym: dermatomycoses, dermatofitiya) — the damages of skin and hypodermic cellulose caused by pathogenic and conditionally pathogenic fungi. Depending on a sort, a type of the activator (see. Fungi parasitic ) and reactions of an organism to its implementation of G. z. to. are divided into four groups: keratomycoses, trichomycoses, epidermomycoses and deep fungus diseases.

Keratomycoses

Contageousness of keratomycoses is small; they are widespread everywhere, a knotty trichosporosis — hl. obr. in the tropical countries. Activators parasitize in a superficial part of a corneous layer of skin, without causing reaction of underlying layers, in a cuticle of a hair. Carry a chromophytosis to keratomycoses (see. chromophytosis ), a trichosporosis knotty (see. Trichosporosis ), trikhonokardioz (see. Trichomycosis axillary ); included in this group also an erythrasma, the activator carry a cut to bacteria now (see. Erythrasma ).

Trichomycoses

Trichomycoses of a vysokokontagiozna, are eurysynusic; hl are ill. obr. children, but it is frequent also adults. A source of infection are sick animals (cats, dogs, mice, etc.) and the person (see. Pilomikoz ). The infection is transmitted at direct contact and through household objects. Activators parasitize in a corneous layer and cause inflammatory reaction of a derma of various intensity, allergic reactions (see. Mikida ); possess only it inherent ability to affect hair, getting through its cuticle; nails are surprised. Carry to trichomycoses trichophytosis (see), microsporia (see), favus (see).

Epidermomycoses

Activators strike all thickness of a corneous layer, often nails, cause inflammatory reaction of a derma (sometimes suppuration), quite often there are allergic reactions. Carry an epidermophitia of feet, an inguinal epidermophitia which differ in high contageousness and prevalence in all countries (see to epidermomycoses. Epidermophitia ), a tinea (a synonym rubromikoz) feet and brushes (see. Tinea ), contagious, meeting in the tropical countries cherepitseobrazny mycosis (see. Mycosis cherepitseobrazny ), black mycosis, and also widespread, but not contagious a candidiasis (see. Candidiasis ) and a geotrichosis of skin superficial (see. Mould mycoses ).

A number of authors trichomycoses, a tinea and an epidermophitia combine in group of dermatomycoses.

Deep fungus diseases

Deep fungus diseases (deep mycoses) of a nekontagiozna, their activators live in the soil; are widespread in the tropical countries, many of them have local character. The USSR meets sporadic.

Mycoses of this group divide into two subgroups.

1. Deep mycoses of skin, the skin which are characterized by primary defeat and hypodermic cellulose, implementation of the activator in earlier injured skin, its distribution on limf, to vessels. In the started cases muscles, bones are surprised, it is very rare — internals. Carry to them: chromomycosis (see), a maduromycosis (see. Madura foot ), sporotrichosis (see), tsefalosporioz (see), a zymonematosis keloid (see. Zymonematoses ), mold mycoses (see), a deep granulematozny candidiasis (see. Candidiasis ).

2. System, visceral mycoses, at which skin is surprised for the second time by limfogematogenny distribution of a fungus. Activators get into an organism with the inhaled dust; initially lungs are surprised. Carry to this group: koktsidiomikoz (see. Coccidioidosis ), histoplasmosis (see), cryptococcosis (see), Gilchrist's zymonematosis (see. Zymonematoses ), a paracoccidioidomycosis (see. Paracoccidioidosis ) and it is conditional actinomycosis (see) which is carried to mikobakterioza now.
