[Clinical cases of microscopic colitis: Diagnosis and treatment issues. Case report].

Currently, there is an increase in the incidence of microscopic colitis. There are difficulties in diagnosing this disease due to the variability of histological signs, variability of morphological changes in the mucous membrane of the colon in different parts of the colon, and the combination in one patient of not only various forms of microscopic colitis, but also other intestinal diseases. The article describes the differential diagnosis, an example of its staging and successful treatment of various forms of microscopic colitis with budesonide (two clinical cases presented).
