자가면역 췌장염의 동반증상 없이 발생한 IgG4 연관 경화성 담관염 = A Case of IgG4 Associated Sclerosing Cholangitis without Clinical Manifestations of Autoimmune Pancreatitis

다국어 초록 (Multilingual Abstract)

IgG4-related systemic diseases are characterized by a diffuse or mass forming inflammatory reaction rich in lymphocytes and IgG4-positive plasma cells (lymphoplasmacytic infiltration), fibrosclerosis of variable organs and obliterative phlebitis. They usually involve various organs including the pancreas, bile duct, gallbladder, salivary gland, retroperitoneum, kidney, lung, and prostate. However, most of them are accompanied by autoimmune pancreatitis, and good response to steroid treatment is one of the hallmarks of this disease. We report a case of an 67-year-old man with IgG4 associated sclerosing cholangitis, who was diagnosed by endoscopic retrograde cholangiopancreatography and successfully treated with steroid therapy.
