Colliquative and/or dirty necrosis are predominantly found in MUC1-positive adenocarcinomas of the pancreas (38) and colorectum (29), whereas the absence of necrotic phenomena is characteristically found in MUC2-positive mucinous adenocarcinomas of the gastrointestinal tract (36,39). Here, MUC2 is linked to mucinous adenocarcinoma.
