Lafora disease is a rare hereditary genetic pathology of the nervous system (a group of progressive myoclonic epilepsies). The distinctive morphological feature of this disease is the presence of specific abnormal structures - polyglucosane bodies («Lafora bodies¼) in the brain tissue, myocardium, liver, and epithelium of the sweat gland ducts. The article discusses the clinical data of the course of Lafora's disease in an 18-year-old patient with a fatal outcome and the results of a post-mortem examination. The diagnosis of Lafora disease was confirmed by genetic analysis data - the presence of a homozygous mutation in the 2nd exon of the EPM2A gene - laforin (chr6:146007412G>A, rs137852915). When analyzing literature, we did not find a description of Lafora's disease cases with a fatal outcome with the presentation of macroscopic examination data at autopsy, as well as the results of a pathohistological examination of altered organ tissues with the morphological manifestations specific for this pathology (Lafora bodies in the the brain, heart, sweat gland epithelium).
