Do Not Overlook Weismann-Netter Syndrome in Differential Diagnosis of Skeletal Dysplasias

Abstract

Weismann-Netter syndrome (WNS), a rare condition, is characterized by an anterior curvature of the bones of the lower limbs, usually bilateral and symmetrical. It was first described in 1954 by Weismann-Netter and Stuhl. We report a 2-year-old girl with typical findings of WNS who was misdiagnosed as having rickets. Our purpose is to draw attention to the WNS in the differential diagnosis of skeletal dysplasias. We think that the true incidence of WNS is probably higher than previously reported; therefore, we would like to emphasize that WNS should be considered in patients who have bowed lower extremities and have been diagnosed as having syphilis or healed rickets.
