MORPHOLOGICAL FEATURES OF CRYPTOCOCCOSIS DEVELOPMENT IN THORAX ORGANS AT PATIENTS WITH VARYING DEGREES OF IMMUNODEFICIENCY
Keywords:
cryptococcosis, fungus morphology, thorax organs, tissue reaction, immunodeficiency.Abstract
The paper presents the results of a study of morphological signs of the mycosis development in thorax organs caused by cryptococcus in patients with various degrees of immunosuppression. The presence, number and localization of fungal cells, their morphological features, as well as the nature and severity of the inflammatory cellular reaction in the tissue of the lungs, pleura and lymph node were studied. It has been shown that the morphological picture in cryptococcal lesions of the thorax organs is represented by fairly diverse morphological changes, which is associated with both different virulence of the fungus and with a different degree of immunodeficiency and the duration of the pathological process. Mostly there are alterative and productivenecrotic granulomatous types of inflammatory response. With complete suppression of immunity, there may be a lack of tissue reaction.
