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.
