comment:
A cyst present in only one islet in a section of pancreas is distinguished from angiectasis based on its large size, lack of an endothelial lining, and the absence of dilation of other vascular spaces ( Figure 1

recommendation:
Islet cysts are uncommon but should be documented when present. A severity grade is not required.references:
