Organized hematoma of the maxillary sinus is a rare, benign condition that can be locally aggressive. The clinical presentation and radiographic appearance can mimic malignancy, but definitive diagnosis is confirmed only after histopathologic evaluation.1,2 A review of the literature revealed only a few cases of organized hematoma of the maxillary sinus. Ozhan et al3 and Steele et al4 each reported a case of pediatric pseudotumor of the maxillary sinus in patients with underlying bleeding disorders (von Willebrand disease and hemophilia A). Unlu et al,5 Tabaee and Kacker,2 and Lee et al1 described cases of organized hematomas of the maxillary sinus in adult patients without underlying chronic sinonasal disease or bleeding disorders. The clinical presentation, radiographic characteristics, and histopathologic findings were similar in all of their cases.
