			==Acinar cell carcinoma==
			{{Main\|Acinar cell carcinoma of the pancreas}}
			===General===
			*Very rare.

			===Cytology===
			Features:
			*High cellularity - '''important feature'''.
			*Lack of ducts.
			*Single cells and small cell clusters with abundant granular (metachromatic) cytoplasm - similar to normal pancreatic acini.
			*Naked nuclei.

			Note:
			*Considered to be a difficult diagnosis.
