[A woman with painful bruising of the fingers]. / Een vrouw met pijnlijke hematomen op de vingers.

We describe a 45-year-old woman with recurrent episodes of painful bruising of the fingers, caused by minimal, everyday traumata. We concluded this to be Achenbach's syndrome (acute idiopathic blue finger), a benign condition that does not require treatment or follow-up. The diagnosis can be made on clinical grounds.
