==Description==

'''Lymphocytic cholangitis''' is a slowly progressive chronic disease characterised by infiltration of the portal areas of the liver with inflammatory cells, mostly [[Lymphocytes|lymphocytes]] and [[B cell differentiation#Plasma cells|plasma cells]].  Bile duct hypertrophy and [[Liver Fibrosis|fibrosis]] are present.  However, lymphocytic cholangitis does not progress to biliary [[Cirrhosis|cirrhosis]].  An immune-mediated aetiology has been postulated but this has not been substantiated to date.  It is rarely associated with [[Pancreatitis - Dog and Cat|pancreatitis]], compared to [[Cholangitis, Neutrophilic]]
