Pedal manifestations of DISH.

Diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier's disease, is an ossifying diathesis characterized by excessive bone formation at specific skeletal sites. The condition is best recognized for its spinal features. However, the tendency toward bone formation is often manifested in extraspinal locations, particularly the foot. The radiographical, pathological, and clinical features of the disorder are reviewed with special emphasis on the foot as a target organ. Abnormalities in the foot that suggest the diagnosis of DISH are emphasized.
