An Atypical Cause of a Child Limp: A Gorham-Stout Disease with a Vanishing Hip.

Gorham-Stout disease (GSD) is a rare bone disease characterized by an abnormal proliferation of endothelial-lined vessels and destruction of the affected bone. As it affects commonly children and young adults, it is associated with significant morbidity and mortality. To date, there is no established treatment strategy for GSD. We report through this observation a rare case of GSD in a child located in the hip and the iliac crest.
