Glikojen depo hastalığı Tip 3’ün dil tutulumu ile likenoid infiltrasyon birlikteliği

Abstract

Glycogen storage disease (GSD) type III is an autosomal recessive metabolic disorder and inborn error of metabolism characterized by a deficiency of glycogen debranching enzymes which is affecting 1/100000 every live birth. Clinical presentation is classified into four groups according to the muscular and liver involvement. GSD IIIa, the most common form of GSD III, primarily affects the liver, cardiac muscle, and skeletal muscle. Treatment mainly involves a high-protein diet, to facilitate gluconeogenesis. A 28-year-old male presented to our outpatient clinic with a 2-month history of white asymptomatic lesions on his tongue. He was diagnosed with GSD type 3 when he was six months old, and he has no other systemic disease, drug use or smoking history. A punch biopsy was performed, in superficial dermis band type lymphohistiocytic lichenoid infiltration was detected, also vacuolization of muscle cells and positive PAS staining were seen histologically. Topical high potent corticosteroids and dietary recommendations were offered to him. We want to present this case because of the rarity of lingual muscle involvement in glycogen storage disorders.
