Angiolipofibroma of the Cecum: A Rare Type of Submucosal Polyp
Figure 1
(a) and (b) show a colonic polypoid submucosal proliferation of mature adipose and fibrous tissue with blood and lymph vessels of different sizes (hematoxylin and eosin stained sections, (a) magnification ×20 and (b) magnification ×40). (c) Weigert’s stain for elastic fibers highlights the internal elastic lamina in arteries (magnification ×100). (d) CD31 stains endothelial cells from blood and lymph vessels (see large lymph vessel at upper right) (magnification ×400). (e) D2-40 stains the lymphatic endothelium while the blood vessels endothelial cells remain negative (magnification ×400).
