ABSTRACT
The article presents clinical observation of a patient with cryptogenic cirrhosis of the liver, a chronic diffuse progressive liver disease, which is manifested by structural rearrange¬ment of its parenchyma. Cryptogenic cirrhosis is cirrhosis of uncertain etiology that lacks definitive clinical and histological criteria for a specific disease. Cryptogenic cirrhosis accounts for nearly 5% to 30% of cases of cirrhosis and nearly 10% of liver transplants. The problem of cirrhosis of the liver is extremely relevant, because this pathology is observed mainly in young and able-bodied people. In addition, it takes the first place among the causes of mortality from diseases of the digestive system. To clarify the diagnosis, laboratory and instrumental diagnostic methods of investigation were performed. Due to severe thrombocytopenia and minor leukopenia, myelodysplastic syndrome was suspected. Metabolic disorders that can be considered as probable in the occurrence of the above-mentioned changes in the liver parenchyma had been ruled out.
