Table 1. ESMG scoring system for inflammation and acinar type.

The left column provides categories to score overall inflammation within ESMG. The second column scores different acinar types (as defined in column three) with by counting acinar types present in an ESMG. Each acinus within an ESMG should only be assigned one category. The bottom cell of this column should represent the total tally of the five different acinar types and should equal all acini within an ESMG. The far right column allows calculation of percentages of each acinar type per ESMG.

Scoring of Each ESMG	Types of Acini (score below)	Definitions of Acinar Types	% Each Acinar Type of Total # Acinar Units
Overall inflammation (score below)	# Mucinous	Pale, plump, glandular cells
0 = none	# Serous	Small dense granules and peripherally located nucleus
1 = mild	# Oncocytic	Eosinophilic (mitochrondria-rich) with central nucleus
2 = moderate	# Dilated Mucinous	Pale mucinous cells with dilated lumen
3 = marked	# Ductular Metaplasia	Ductal-type epithelium with dilated lumen
	Total # of Acinar Units	Calculated as sum of five different acinar types	Should add to 100%
