We present a case of pseudotumor. The patient was a 51 year old male, complaining of unilateral exophthalmos of the right eye for about 10 years. It was much aggravated during last a year. Past and family history were non-contributory. At the first examination on the 10th of May, 1971, the left eye was recorded normal. The right eye showed H. M. /50cm. in vision, proptosis (18mm difference in both eyes), limitation of ocular motility, exposure keratitis, and pallor disk in funduscopy. The skull X-ray showed a radiopaque density with enlarged orbital cavity but no evidence of bone destruction.
The patient was admitted to our department on the 13th of May, 1971. on the seventh hospital day, a child fist sized firm tumor mass removed through anterior approach. The right eye had also enucleated.
Grossly the mass had a gray color, partially discolorated and have alveolar structures. Microscopically lymphoid follicles were separated by fibrous occasionally hyalinized fibrous connective tissue. Also occasional hemorrhagic foci and infiltration of eosinophils were seen.
