How long does trichophytosis last?
Without treatment, trichophytosis in some children can last for years. The disease, as a rule, spontaneously cures only when puberty occurs. In some patients, mostly women, untreated trichophytosis manifests itself differently, turning into chronic trichophytosis. In its pathogenesis, an important role is played by disorders of the autonomic nervous system, endocrinopathy (hypogenitalism, hypercorticism, diabetes, hypovitaminosis A, etc.). It should be borne in mind that chronic trichophytosis can be observed in children. When examining patients with chronic trichophytosis pay attention to the condition of the scalp, smooth skin and nails. The most common manifestations of chronic trichophytosis on the scalp are: single hair broken in the mouth of hair follicles near the surface of the skin, hair in the form of black dots - "black-spotted" trichophytosis), more often in the occipital and temporal areas, small round atrophic scars (1-2 mm in diameter ) and insignificant small-plate scaling.

What causes trichophytosis?
The causative agent of this form of trichophytosis is Trichophyton tonsurans, s. Crateriforme, T violaceum. The source of infection is a patient with trichophytosis. Infection occurs by direct contact with the patient or through his things (headgear, nagelnoe and bed-clothes, combs), which the patient used. The patient can become infected in hairdressing salons, kindergartens, schools and other children's institutions. Decreased immunity system, endocrinopathies create good conditions for the development of the disease. By frequency, this mycosis ranks second after microsporia. The causative agents of trichophytosis are divided into groups, depending on the type of damage to the hair. Two main groups are distinguished: endothrix (endotriks) - fungi affecting the inner part of the hair, and estotrix (ectotriks) - vegetative predominantly in the outer layers of the hair. All trichophytons endotrices are anthropophiles, transmitted only from person to person. They cause superficial lesions of the skin, scalp, and nails. Ectotriks are zoophiles, parasitizing mainly on animals, but capable of infecting humans as well. Compared with the fungi of the endotrix group, they cause a more pronounced inflammatory skin reaction in a person.
