[Osteogenic aneurysmal orbital cysts].

The orbital form of this osseous tumor-like dystrophy is quite rare. The illustrated description of a new case is reported and the 13 cases of the literature reviewed. The main clinical and radiological data as well as the different treatments are commented upon. The anatomo-pathologic discussion focuses on the morphological aspects, hypotheses on the pathogenesis and differential microscopic features of the lesion as compared to other osseous lesions of the orbital bones.
