Sarcoidosis presenting as multiple pulmonary nodules and nephrotic syndrome.

A 56 year old man presented with thrombophlebitis, nephrotic range proteinuria and multiple pulmonary nodules. A renal biopsy showed membranous glomerulonephritis, and after a thoracotomy a diagnosis of sarcoidosis was established. A pulmonary nodular pattern is unusual in sarcoidosis and is often mistaken for malignant disease. The association of this type of pulmonary involvement and membranous glomerulonephritis as the presenting form of sarcoidosis has not previously been described.
