Abstract

IgG4‑related disease is a recently recognized clinical entity. It is characterized by diffuse organ swelling or mass formation, a dense lymphoplasmacytic infiltrate rich in IgG4‑positive plasma cells with fibrosis and typically an increased serum IgG4 concentration, which may affect various organs. An 80‑year‑old woman with an otherwise unremarkable previous medical history was revealed to have a renal mass that was indicative of renal malignant carcinoma, for which a radical nephrectomy was performed. The mass was diagnosed as an IgG4‑related inflammatory pseudotumor, which was histopathologically confirmed. The patient is currently well without evidence of IgG4‑related disease at 3 months post‑surgery, and did not require any additional therapy.
