Three Cases of Organized Hematoma of the Maxillary Sinus: Clinical Features and Immunohistological Studies for Vascular Endothelial Growth Factor and Vascular Endothelial Growth Factor Receptor 2 Expressions

<div>The lesion consisted of dilated vessels, hemorrhage, fibrin, exudation, and fibrosis with hyalinization. Atypical cells are not seen (hematoxylin and eosin staining; (a) original magnification, ×40; (b) original magnification, ×200). VEGF is expressed in endothelial and inflammatory cells around the dilated vessels ((c) original magnification, ×200). VEGFR2 is expressed on the vascular endothelial cells of the dilated vessels ((d) original magnification, ×400).</div>
