Hemophilia of orbit.

Hemophilic pseudotumor is an uncommon complication of factor VIII and IX deficiencies in the coagulation cascade and occurs in a wide spectrum of bones and soft tissues. We present a six-year-old boy with hemophilic pseudotumor localized in the right orbit. He showed a favorable response to radiation therapy after unsuccessful treatment with factor VIII replacement therapy with no recurrence till eight months. Radiotherapy in the treatment of pseudotumors in hemophiliacs should be strongly considered, particularly in severely affected patients who do not respond to conservative therapy.
