Parasitic sycosis is a form of zooanthropophilic trichophytosis, and therefore is more common among the rural population, which has some difficulties with the availability of qualified medical care. Moreover, being a type of sycosis and having similar clinical manifestations, it often becomes the cause of diagnostic errors. Coverage of this problem, in our opinion, is relevant for dermatologists. A review of the literature on the problem of sycosis including classification, clinical manifestations, differential diagnosis and treatment tactics was carried out. Taking into account similar clinical manifestations and a specific diagnostic error, a description of a clinical case of parasitic sycosis is presented.
