RESUMEN
Glycogen storage disease (GSD) type Ia is a rare inherited metabolic disease characterized by glucose-6-phosphatase (G6Pase) deficiency, which results in many metabolic problems, such as fasting hypoglycemia, lactic acidosis, hyperuricemia, and hyperlipidemia. The metabolic derangements may result in long-term complications, including growth retardation, gout, hepatic adenomas, and renal disease. A 26-year-old male was admitted with general weakness, multiple subcutaneous mass-like lesions, and hepatomegaly. He was diagnosed as GSD type Ia through analysis of the G6Pase gene. This disease is found mainly in childhood, but we diagnosed a case of GSD type Ia during a work-up of arthralgia and hepatomegaly in an adult patient. We report this case with a review of the literature
