Organizing hematomas are rare benign tumors and appear as masses that are composed of neovascularization with organizing fibrotic tissue in a hematoma. Although histologically benign, this condition may be clinically progressive. Radiological findings can range from a benign appearance to a more aggressive process, including bony erosion. Organizing hematoma of the maxillary sinus is a rare clinical disease. To our knowledge, only a few cases have previously been published, and most were without bleeding history and disorders. Until now, all of the reports about this lesion have discussed the clinical course, and no previous report has closely considered pathologic findings and pathogenesis. We report three cases of organizing hematoma of the maxillary sinus presenting with an enlarging maxillary sinus mass.
