A rare form of leishmaniasis, identified in the Russian Federation

Abstract

Diffuse cutaneous leishmaniasis is a rare form of cutaneous leishmaniasis characterized by an inadequate immune response of the host cells to parasitic invasion (weak T-helper (Th)1 response or Th2 response with the production of interleukin (IL)-4 and IL-10). The characteristic features of the disease include diffuse nodular eruption, masquerading as leprosy and a frequent association with immunosuppression (HIV co-infection, for example). The Russian Federation is a non-endemic country for leishmaniasis, but this disease can be brought into the country by tourists, immigrants, refugees and military personnel. A clinical case of diffuse cutaneous leishmaniasis and HIV co-infection is presented. The patient was a citizen of Uzbekistan, a country endemic for leishmaniasis. The authors were unable to find domestic scientific publications describing cases of diffuse cutaneous leishmaniasis detected in the Russian Federation. The presented clinical case of diffuse cutaneous leishmaniasis in a patient with HIV is the first in the Russian literature.
