Pompe Disease Complicated with Appendicular Torsion: A Rare Concurrence.

Abstract

Pompe disease, also known as Glycogen Storage Disease Type II, is a rare disorder of glucose metabolism caused by congenital acid alpha-glucosidase (GAA) deficiency. A large amount of glycogen accumulates in the lysosomes, causing these to swell and rupture. Its incidence is about 1 in 40,000 to 1 in 50,000 newborns. The main features are hypotonia and cardiomyopathy. Only a few clinical cases of Pompe disease have been reported, and appendicular torsion has rarely been observed. Herein, we report a case of Pompe disease combined with appendicular torsion, both of which were diagnosed on autopsy pathology. The clinical diagnosis of this disease is difficult in developing countries, and it is mostly misdiagnosed as other types of heart disease. Once the clinical symptoms worsen, most of them die within a short period. Therefore, screening for neonatal genetic metabolic diseases for early diagnosis and treatment should be carried out.
