Mauriac syndrome is a rare and underdiagnosed complication of type 1 diabetes mellitus (T1DM). It is characterized by growth retardation, delayed puberty, Cushingoid features, hepatomegaly, and increased transaminase levels. The term glycogenic hepatopathy has been used to describe patients with poorly controlled T1DM and glycogen overload in the hepatocytes but without all the features of Mauriac syndrome. Although rare, glycogenic hepatopathy is reported to be the main cause of hepatomegaly in young patients with T1DM. We report two cases of glycogenic hepatopathy in children with poorly controlled T1DM. Both children had hepatomegaly, elevated liver enzyme levels, and elevated lactate levels. A liver biopsy confirmed the diagnosis of glycogenic hepatopathy in both patients. In conclusion, hepatomegaly with elevated liver enzymes, negative infective and metabolic screenings and persistently elevated plasma lactate levels should raise the suspicion of glycogenic hepatopathy in poorly controlled T1DM. Early diagnosis and improvement in glycemic control are the mainstays of treatment, which can prevent long-term complications.
