Balkan endemic nephropathy BEN is a fatal kidney disease that is known to occur only in clusters of villages in alluvial valleys of tributaries of the Danube River in Bulgaria, Romania, Yugoslavia, Bosnia, and Croatia The confinement of this disease to a specific geographic area has led to speculation that an environmental factor may be involved in the etiology of BEN
