Nasal hemophilic pseudotumor in a patient with mild hemophilia A and allergic rhinitis.

Hemophilic pseudotumor is a rare complication, even in patients with severe hemophilia. Herein we report on a case of hemophilic pseudotumor in a patient with mild hemophilia A and allergic rhinitis, initially suspected to be a nasal tumor. The pseudotumor was cured by supplementation with recombinant factor VIII concentrates, and medication for allergic rhinitis. Pseudotumor should always be considered in hemophiliac patients, even in those with only mild deficiency of coagulation factors.
