Figure 3From: Ectopic pancreatic-type malignancy presenting in a Meckel's diverticulum: a case report and review of the literatureHistology and immunoprofile of pancreatic type adenocarcinoma. The malignant glands (arrows in A) are highlighted by cytokeratin expression (B). The poorly differentiated single tumour cells infiltrating the tissue surrounding the ectopic pancreatic islets are difficult to identify with the conventional haematoxylin and eosin (H&E) section (arrows in C), but are highlighted by cytokeratin (D). The islets (E) express neuroendocrine markers, and specific pancreatic islet cell markers insulin (F) and glucagon.Back to article page
