[Tumors and pseudo-tumoral dysplasias of orbital bones].

Abstract

The authors review and study, especially from the anatomo-pathological aspect, the different tumours and pseudo-tumoural dysplasias of the orbital bones taken from the collection of the Laboratory of Ocular Pathological Anatomy of the Hotel-Dieu in Paris. They demonstrate the particular frequency of osteomas and fibrous dysplasias and discuss the orbital predisposition of giant cell tumours of bone. Finally they underline the existence of vascular bone tumours and aneurysmal cysts.
