OSSEOUS TUMORS OF THE ORBIT

Abstract

Although bony growths within the orbit are relatively frequent, a review of the literature fails to produce a complete description of them from an ophthalmologist's point of view. For this reason we present two cases of bony growths of the orbit producing exophthalmos and other eye conditions, which we trust may contribute somewhat to the knowledge of this little studied aspect of ophthalmology. It has been customary to consider nearly all new bony growths involving the skull and facial bones as Paget's disease. In his original description, however, published in 1870, Paget apparently did not try to classify these new bony growths in any way. If the new bone formation is limited to the bones of the skull, the term leontiasis ossea, as given by Virchow, would seem to be a better descriptive term to use. In the so-called Paget's type of tumor growth, the bones concerned in the formation
