Case ReportsCutaneous lymphatic malformations in disappearing bone (Gorham-Stout) disease: a novel clue to the pathogenesis of a rare syndrome.
Gorham-Stout disease is an unusual, progressive syndrome of unknown etiology characterized by mono- or polyostotic osteolysis most often affecting children and young adults. The onset is insidious and the disease progresses to extensive and potentially disabling osteolysis often unresponsive to therapeutic intervention. Although bone and soft tissue lesions are the most frequent manifestations of Gorham-Stout disease, skin lesions can occur and may provide a clue to the pathogenesis of this rare syndrome. ⋯ A vascular process with angiomatous histological features is considered to be the pathological hallmark of Gorham-Stout disease, but the specific type of this vascular process is still under debate. Our report highlights a lymphatic malformative nature of Gorham-Stout disease, thereby contributing to a better understanding and characterization of this rare disease entity.
