Image #1: Type: Gross Organ/System: Pancreas Description: Acinar Cell Carcinoma. Cut surface of an acinar cell carcinoma displays large yellowish brown to red nodules, separated by fibrous strands and frequently showing necrotic foci.
	Image #2: Type: Micro Organ/System: Pancreas Description: Acinar Cell Carcinoma. At low magnification the markedly cellular tumor tissue shows gross lobulation by broad fibrous strands. Within the large tumor lobules there is only scant stroma.
	Image #3: Type: Micro Organ/System: Pancreas Description: Acinar Cell Carcinoma. This tumor shows a mixed pattern, with acinar areas alternating with trabecular and solid formations.
	Image #4: Type: Micro Organ/System: Pancreas Description: Acinar Cell Carcinoma. The nuclei are somewhat irregular in size. In acinar formations they show a polarized arrangement.
	Image #5: (414133) Type: Micro Organ/System: Pancreas Description: Acinar Cell Carcinoma. This tumor shows a pure acinar pattern, reminiscent of normal pancreatic acinar tissue.
	Image #6: (414134) Type: Micro Organ/System: Pancreas Description: Acinar Cell Carcinoma. The tumor cells have abundant cytoplasm, which is finely granular and PAS positive in its’ apical portion.
	Image #7: Type: Micro Organ/System: Pancreas Description: Acinar Cell Carcinoma. This area shows dilated acini forming “microglandular” structures.
