Prader-Labhart-Willi Syndrome is a complex, multisystem sporadic disorder which presents during childhood and proceeds into adulthood. The major features include infantile hypotonia, developmental delay, hypogonadism with abnormal sexual maturation, mental retardation and behavior abnormalities, short stature with small hands and feet, massive obesity with diabetes mellitus, dysmorphic facial features, and marked dental caries and enamel hypoplasia. Recently, a deletion of chromosome 15 has been found in a large percentage of these patients, but the exact cause and genetic transmission has not yet been determined. Two cases of Prader-Labhart-Willi Syndrome are presented with emphasis on the differential diagnosis of enamel hypoplasia associated with sexual maturation.
