Neutrophils in the surface epithelium (1, 3, 5, and 7) or crypt epithelium (2, 4, and 6) and the presence of an erosion or ulceration (major grade 5): the numbers indicate the number of biopsies involved and assessed by one observer. Neutrophils in the crypts were less common when an erosion was present.
