Arthropathy-like findings and a carpal tunnel syndrome as the presenting features of Scheie syndrome: Three cases from the same family.

Gökay S, Kardaş F, Kendirci M, Sözeri B. Arthropathy-like findings and a carpal tunnel syndrome as the presenting features of Scheie syndrome: Three cases from the same family. Turk J Pediatr 2018; 60: 344-347. Mucopolysaccharidosis (MPS) type I is a rare autosomal recessive disease caused by a deficiency of the lysosomal enzyme α-L-iduronidase. MPS I is divided into three subtypes based on the severity of symptoms: Hurler, Hurler-Scheie, and Scheie syndrome (severe, intermediate, and mild forms, respectively). Musculoskeletal involvement may be the only presenting sign in the patients with Scheie syndrome. We have reviewed three cases with prominent features of carpal tunnel syndrome (CTS) at the onset of their disease. Diagnosis was delayed in almost all cases (range 16-19 years). During one year of follow-up period, alleviations of the pain in the hands of patients were observed after enzyme replacement therapy. MPS type I should be considered in the differential diagnosis of the patients with CTS in the first and second decades of life, particularly with stiffness of the fingers and difficulty using the hands without an inflammatory component. An increased awareness of the disease may contribute to more accurate diagnosis, and patients may benefit from early intervention.
