Figure 6: Mucinous adenocarcinoma. Panel A Photomicrograph (original magnification, Ť300; hematoxylin-eosin stain) demonstrates large mucin pools with intervening cords of malignant cells. Panel B CT scan shows a large mucinous adenocarcinoma of the cecum with scattered areas of low attenuation (arrowheads), as well as a punctate calcification (curved arrow). The other area of high attenuation represents intraluminal barium (straight solid arrow). Also note the round soft-tissue masses within the mesentery (open arrows), representative of adenopathy. In the presence of a colon mass, any adenopathy within the mesentery should be viewed as highly suspicious for metastatic disease. Panel C Photograph of the gross specimen demonstrates the large cecal mass (large arrow) and several variably sized pale white lymph nodes (small arrows) along the course of the superior mesenteric artery. Most lymph nodes affected with metastatic disease are less than 5 mm in size and are often not appreciated on CT scans.
