Cases of immunoglobulin G4-related disease (IgG4-RD) along with renal cell carcinoma are extremely rare. In this study, we report on a 61-year-old male who was diagnosed with both IgG4-RD and renal cell carcinoma. We examined the period beginning 13 years before the renal cancer diagnosis to two months after surgical removal of the tumor.
IgG4-RD is an immune-mediated disease that leads to the formation of multi-system masses. It affects almost every organ and is challenging to diagnose and cure in clinical settings [1]. In this case, we report the clinical data, surgical methods, pathology, and immunohistochemical characteristics of a patient who was diagnosed with IgG4-RD 7 years ago and diagnosed with a tumor in the left kidney by our department in August 2020.
