Case Discussion
Marble bone disease is a rare hereditary disorder due to defective osteoclast function with failure of proper reabsorption, producing sclerotic bone. There are two types:
infantile autosomal recessive type
benign adult autosomal dominant type
Differential diagnosis should be made with renal osteodystrophy, fluorosis, melorheostosis
