1-3) The histologic diagnosis of GVHD is historically based on the 1974 Lerner et al (4) criteria that qualify grade 2 GVHD as destruction of crypts with apoptotic crypt abscesses, grade 3 GVHD as focal mucosal necrosis with denudation, and grade 4 GVHD as diffuse mucosal necrosis with denudation.
Large numbers of crypt abscesses are probably indicative of either superimposed infection or a separate diagnosis such as UC.
Be aware that some histologic features normally associated with inflammatory bowel disease, including crypt irregularity and neutrophilic cryptitis and even crypt abscesses, may be encountered in a minority of those with LC, and that the presence of one or more of these features should not necessarily be interpreted as evidence incompatible with LC.
