title: [IgG4 associated nephritis and recurrent hemoptysis: Case report].
abstract: IgG4 disease is a multi-systemic condition involving pancreas, salivary glands and lymph nodes. Less frequently, it causes interstitial nephritis and involves the lungs. We report a 58 years old male with a four years history of hemoptysis and renal dysfunction characterized by hematuria and proteinuria, responsive to steroidal therapy. The renal biopsy established the diagnosis of IgG4 associated interstitial nephritis. Lung involvement was considered secondary to the same systemic disease.
