title: Osseous metaplasia within tumours. A review of 11 cases.
abstract: Although numerous mechanisms that involve characteristic histological changes have been suggested to explain the development of heterotopic ossification within tumours the precise morphogenesis remains obscure. The histological features of 11 tumors that contain heterotopic bone are described with a particular emphasis on those features that are thought to predispose to ossification.
