Figure 1. Expression of CD74 (top row) and MHCII (bottom row) in the same areas of three representative tumors as determined by immunohistochemistry.

Figure 1

These three cases scored as CD74 strong positive / MHCII strong positive (panels A and D), CD74 weak positive/MHCII weak positive (panels B and E), and CD74 negative/MHCII negative (panels C and F) for tumor cell expression. Main images taken at 200× original magnification with insets showing detail within the image. Note that TIL staining positive for CD74 and MHCII are present in stromal and epithelial compartments of all cases but were not included in scoring.
