The kidney biopsy features and the radiologic involvement of typical organs (kidneys, prostate, aorta and pancreas)[2] were the key to IgG4-RD diagnosis. Although IgG4-RD can masquerade as cancer, IgG4-RD may be associated with lymphoma and co-exist in the same site of biopsy, as in our case.[3] A recent meta-analysis suggested that patients with IgG4-RD have a higher risk of overall cancer, especially pancreatic and lymphoma.[4] Conversely, malignancy may be associated with subsequent IgG4-RD development.[5] The underlying pathophysiological link of this association remains unclear.
