title: [Occupational koilonychia].
abstract: Over a period of 10 years a 57-year-old patient mainly repairing oil-burner gradually developed spoon-like deformations of his finger nails. A 47-year-old patient observed similar alterations working as a butcher for 4 years. We want to stress the occupational induction of the disease and its therapeutical consequences.
