Photo Gallery. Parasitic dermatoses.

Parasitic dermatoses retain significance due to their high prevalence in contemporary society. The most frequently encountered diseases are scabies and pediculosis. These dermatoses are commonly observed in groups of individuals living together (nursing homes, psychiatric hospitals, hospices, dormitories, children's homes, barracks). Poor socio-hygienic conditions and non-compliance with personal hygiene rules also contribute to disease development.
Scabies is a dermatоsis-zoonosis caused by the scabies mite Sarcoptes scabiei hominis. It is characterized by intensely pruritic eruptions and the presence of scabies burrows, which is a pathognomonic sign. It develops at any age, although it is most frequently encountered in children and elderly individuals. Severe forms of the disease include scabies lymphoplasia, scabies erythrodermia, and Norwegian scabies.
Pediculosis is caused by blood-sucking insects — lice. Three species of lice parasitize human skin: head louse (Pediculus humanus capitis), body louse (Pediculus humanus corporis), and pubic louse (Pthirus pubis). Complications of pediculosis include pyodermias and allergic dermatitis; it should also be noted that lice are vectors of typhus fever.
Myasis is a parasitic disease caused by larvae of dipterous flies (Dermatobia hominis). Lesions are frequently detected on the face and scalp, presented as nodules from which serous-purulent contents may be discharged.
Onchocerciasis ("river blindness") is a chronic parasitic disease caused by the filarial nematode Onchocerca volvulus. It is characterized not only by skin involvement but also frequently by severe ocular damage.
Cutaneous leishmaniasis is a vector‑borne human disease attributable to the unicellular, flagellated protozoan Leishmania tropica. The infection is transmitted by sandflies of the genus Phlebotomus, with Phlebotomus papatasi being the principal vector. 

Trombidiasis is a disease caused by the penetration into the skin of larval mites of the genus Trombidiidae (family Trombiculidae). The infection manifests as local inflammation, papule formation, and erythema at the site of larval insertion. 

The photo gallery presents various cases of parasitic dermatoses and their causative agents.
