Immunoglobulin G4-Related Disease with Several Inflammatory Foci

Abstract

We herein report the case of a 62-year-old Japanese man who presented with jaundice, dry eyes and abdominal discomfort. Imaging studies revealed swelling of the periorbital tissue, parotid and submandibular glands, pulmonary hilar lymph nodes, pancreas, bile ducts, gall bladder walls, bilateral kidneys, arterial walls and prostate. A significant increase in the serum level IgG4 was seen, and the patient was diagnosed with IgG4-related disease after undergoing a biopsy of the pancreas and prostate. We herein report a case of IgG4-related disease with multiple ten organ involvement at the onset of the disease that was successfully treated with prednisolone (PSL) therapy.
