Abstract
The authors report a case characterized by a marked swelling of the maxillary bone and nasal obstruction.
The specimen obtained during the exploration of the affected bone showed pathological characteristics similar to fibrous dysplasia of the maxillary bone.
The patient however developed swellings of the knee joints after the operation and was found to have hemophilia.
A careful study of the maxillary bone specimen and the clinical course implied that the changes seen in the maxillary bone were reactive osteogenic process to the pathology caused by hemophilia.
