Behçet's syndrome and focal segmental glomerulosclerosis with nephrotic syndrome - successful treatment with etanercept .

Behçet's syndrome (BS) often presents with aphthous and genital ulcers, uveitis, and erythema nodosum. Renal involvement has been reported with most cases presenting with renal amyloidosis, IgA nephropathy, or crescentic glomerulonephritis. We describe a case of a 49-year-old woman with relapsing BS symptoms coinciding with new-onset development of nephrotic syndrome.
