The article presents a clinical case of cross-syndrome of autoimmune hepatitis type 1 with primary sclerosing cholangitis. The main symptoms, laboratory and instrumental criteria of these diseases are discussed. Detection of specific antibodies is necessary for an accurate diagnosis. Interpretation of changes in the colon obtained by stepwise biopsy requires special attention. The described morphological picture does not allow to make an accurate diagnosis, it can be regarded as initial manifestations of Crohn's disease, microscopic or eosinophilic colitis, signs of worm-parasitic invasion. An example of a differential diagnostic search in such a situation is discussed.
