Scheie syndrome is a rare inborn error of metabolism, a mucopolysaccharidosis in which deficiency of the lysosomal enzyme alpha-L-iduronidase leads to tissue accumulation of mucopolysaccharides. Scheie syndrome is a forme fruste of Hurler syndrome (gargoylism), and some patients have the phenotype of Hurler-Scheie compound syndrome. The craniofacial abnormalities include coarse facies, mandibular condylar hypoplasia, retarded tooth eruption, and cystic jaw radiolucencies--particularly about the molars. Corneal clouding may lead to blindness but, in contrast to some other mucopolysaccharidoses, mental handicap is rare in Scheie syndrome. Cardiac valve incompetence is common, as are recurrent respiratory infections. Two brothers with Hurler-Scheie syndrome are presented and the oral and systemic complications each patient had described. The syndrome is discussed with particular reference to the orofacial features.
