Abstract

Introduction: Mucopolysaccharidoses are congenital, hereditary disorders of metabolism, caused by deficiency of vital enzyme. As a result of this the products of metabolism accumulate and settle in tissues and body organs (liver, spleen, heart, brain) and cause malfunction. Children mostly thrive well initially, clinical manifestation of illness are obvious in future development. The II type mucopolysaccharidosis, well-known as Hunter syndrome, affects predominantly boys. In the clinical picture there is typical small figure, short neck, macrocephalia, prominent forehead, flat root of nose, hard-featured, fingers with flex contraction, large abdomen and mental retardation. Stomatological report include poor labial closure and macroglossia manifested in opening of the mouth, macrocheilia, wide dental arches and dentition with spaces. Suspicion for Hunter syndrome follow from clinical examination of the patient, the diagnosis is supported by analysis of urine and definitively confirmed by molecular genetical examination. The transplantation of haematopoietic cells or more frequently the substitution of missing enzyme are used in the therapy.

We take care about this patient for nine years, he was recommended in our ward by the pediatrician at the age of five years and six month.
