[Glycogenic hepatopathy/hepatic glycogenosis: an underappreciated but benign and reversible diabetic complication].

Almost 100 years ago, the French physician Pierre Mauriac described a syndrome named after him, resulting from poorly controlled type 1 diabetes, with growth retardation, delayed puberty, Cushingoid features and hepatomegaly. With modern diabetes care, this is very rare but does occur; however, despite the condition having important clinical implications and being easily treatable, this diabetes complication remains relatively unknown. We present here an authentic patient case in the form of a young man with glycemically poorly controlled type 1 diabetes who developed hepatomegaly, hyperlactatemia and histopathological changes in the liver consistent with glycogenosis, a state readily reversed by normalization of glycemia.
