Authors represent the Russia’s first clinical case description of a pediatric patient with ulcerative colitis whose diagnosis was combined with Lambert-Eaton myasthenic syndrome (LEMS), a rare autoimmune disorder of neuromuscular junction transmission. The observed case draws specialists’ attention to the complexity of diagnosis and the importance of a multidisciplinary approach in the diagnosis and management of such patients.
