We present a case of scleroderma overlap syndrome with systemic lupus erythematosus (SLE) including complications of both scleroderma renal crisis and lupus nephritis. Our patient was initially diagnosed with undifferentiated connective tissue disease in 1996. A diagnosis of scleroderma was made in 2010 after she developed scleroderma renal crisis. She remained stable until 2016, when she presented with Salmonella bacteremia, renal failure, nephrotic range proteinuria and microscopic hematuria. Laboratory findings were consistent lupus with positive ds-DNA, hypocomplementemia and repeat renal biopsy showed lupus nephritis.
