Granulomas in the pancreas are not equivalent to granulomatous pancreatitis. 2. Apart from foreign body granulomas on the pseudocyst margin (endogenous foreign body), and around the past operation stitch rests (exogenous foreign body), we have found thirty-six cases of granulomas in 1000 cases of chronic pancreatitis. Occasionally one could find granulomas around Ethibloc residues. The frequency could not be exactly determined, because most of Ethibloc reacted parts of the glands were not operated (removed). 3. We could not clarify the etiology in 20 cases (so-called cryptogenous granulomas). There were 7 cases of vessel granulomas, partly with complete obliteration of the arteries: arteriitic granulomas. The granulomas were always found in many arteries of the same caliber, never in solitary vessels. These findings were always preceded by arteriography. 4. Granulomatous pancreatitis was organ manifestation in primary Syphilis (2 cases) and primary M. Boeck (2 cases). We found fungal granulomas in AIDS. 5. Granulomatous pancreatitis plays a subordinate role in the complete picture of the basic disease; but it can cause an obstructive icterus and show a tumoral symptom.
