Iron staining in colonic tissue between cases and controls. Sections of colonic tissue (adenocarcinoma for cases, healthy mucosa for controls) were tested for presence of iron accumulation using the Perls’ Prussian blue staining. Cases with presence (A) and absence (B) of iron accumulation were compared to controls with presence (C) and absence of iron accumulation (D) and presented as 20X magnification. There was more iron accumulation detected in cases than controls (n = 6/20; 30%; n = 1/20; 5%; McNemar’s test: χ2 = 5.0; p < 0.05).
