Intravascular Papillary Endothelial Hyperplasia Associated with Venous Pool Arising in the Lower Lip: A Case Report
Figure 3
(a) A thrombus (inside green circles) was observed in the expanded blood vessels (blue arrows) with venous pool (yellow arrows) using hematoxylin-eosin staining (Original magnification, 3.2; Bar, 1000 micro meter). (b) The figure shows the area inside the black square of Figure 2(a). Proliferated endothelial papillary cells were observed. Expanded elastic fibers (yellow arrows) are present on the blood vessel surface using hematoxylin-eosin staining (Original magnification, 16; Bar, 100 micrometer).
