N2 - Lymphoplasmacytic sclerosing pancreatitis (LPSP) represents a distinctive form of chronic pancreatitis characterized by diffuse fibroinflammatory infiltrates that can involve both the pancreatic ducts and acinar parenchyma. Several cases of inflammatory infiltrates within the gallbladder have been reported in association with LPSP, but the spectrum of gallbladder pathology in patients with LPSP has not been systematically reviewed. Many patients with LPSP have distal CBD fibrosis, strictures, and inflammation, features that overlap somewhat with primary sclerosing cholangitis (PSC). In PSC, a pattern of gallbladder pathology termed "diffuse acalculous lymphoplasmacytic chronic cholecystitis" has been previously described as showing a triad of diffuse, mucosal-based, plasma cell-rich inflammatory infiltrates. We studied 20 gallbladders from patients with LPSP and compared them with 20 gallbladders in PSC, 20 gallbladders with chronic cholelithiasis, and 10 gall-bladders from patients with benign (non-LPSP) pancreatic disease. The following features were evaluated: degree and composition of mucosal inflammation and deep (mural) inflammation, lymphoid nodules, metaplasia, dysplasia/neoplasia, fibrosis, muscular hypertrophy, Rokitansky-Aschoff sinuses, and cholesterolosis. The majority (60%) of gallbladders in LPSP contained moderate or marked inflammatory infiltrates and lymphoid nodules, frequencies similar to PSC but significantly higher than in chronic cholelithiasis and benign non-LPSP pancreatic disease. LPSP gallbladders received the highest scores for deep inflammation of all groups, and 35% of LPSP gallbladders showed transmural chronic cholecystitis. Overall, "diffuse lymphoplasmacytic chronic cholecystitis" was present in 50% of PSC cases and 25% of LPSP cases, but in only 5% of chronic cholelithiasis and none of non-LPSP benign pancreatic disease. Mucosal inflammation in LPSP gall-bladders correlated significantly with the presence of inflammation in the extrapancreatic portion of the CBD. These findings suggest that inflammatory pathology of the gallbladder is frequently associated with LPSP and that it is part of the spectrum of biliary tract disease in these patients, rather than a simple reflection of the pancreatitis itself.
