An Acute Blue Finger: A Case of Achenbach’s Syndrome

Abstract

Achenbach’s syndrome, also known as paroxysmal finger haematoma, is a rare condition that results in spontaneous bruising and pain in one or more fingers. Despite its benign and self-limiting course, the remarkable clinical presentation can suggest serious vascular and haematological disease leading to unnecessary referrals and invasive investigations. The authors present the case of a 60-year-old woman with an acute painful and bruised finger. All other physical findings and investigations were normal, except for autoimmune thyroiditis. Based on the clinical presentation and course, the diagnosis of Achenbach’s syndrome was made and the symptoms resolved without treatment.
