Invasive Mucinous Adenocarcinoma Associated with Adjacent Sessile Serrated Lesion of the Appendix Vermiform: A Case Report
Figure 2
(a) SSL in the root of the appendix. (b) SSL is regionally observed in the right half of the epithelium, while nondysplastic epithelium can be observed in the left half. SSL shows the loss of hMLH-1 expression; however, a weak to moderate reactivity is preserved in the deep part of the crypts. A hMLH-1 positive control was evaluated on nondysplastic epithelium. The scale bars indicate 250 micrometers.
