Candida lesion of Palatine tonsils was studied in 32 HIV-infected patients in the late stages of the disease using histological and cytological methods. There were used conventional methods during pathomorphological studies of palatine tonsils tissue fragments obtained by biopsy, and smears from the surface of the organ. It was found that micromycetes Candida spp. were located in association with various bacteria (mainly Streptococcus spp.), as well as Cryptococcus spp., with the formation of the biofilms, both on the surface of the Palatine tonsils and in the depth of their parenchyma. We revealed the minimal response cellular protective reaction to the deep introduction of the pathogen. Mycosis proceeded against the background of pronounced follicular lymphoid depletion of the tissue of the Palatine tonsils. The examined patients represent a risk group for invasion of Candida micromycetes into the vascular channel and their dissemination with the development of generalized candidiasis.
