A Painful Blue Thumb: A Case of Achenbach's Syndrome

Abstract

Achenbach syndrome is a rare, self-limiting condition, which causes paroxysmal bruising in the hand or fingers. Etiology is still unknown. The acute phase can be very alarming, and could suggest a more serious vascular disease. Clinicians should be aware of the existence of this condition and not undertake needless invasive investigations. © 2005 Elsevier Ltd. All rights reserved.
