Panel A: Anti-Eph B3 immunhistology (a) and anti-E-cadherin immunhistology (b) in a patient with a poorly differentiated esophageal adenocarcinoma. Eph B3 immunhistology is negative. The E-cadherin immunhistology shows a faint cytoplasmatic reaction. 40-fold magnification. Panel B: Anti-Eph B3 immunhistology (a) and anti-E-cadherin immunhistology (b) in a patient with a moderately differentiated esophageal adenocarcinoma. The Eph B3 shows a strong positivity. The E-cadherin shows a moderate (1+) reaction of the tumor cell membrane. 40-fold magnification. Eph B3, ephrin B3.
