Achenbach's syndrome revisited.

BACKGROUND Achenbach's syndrome, also known as paroxysmal finger hematoma, is a rarely reported clinical disorder with recurring, sudden bruising of the volar part of a finger, appearing spontaneously or after minor trauma and resolving completely within days. PATIENTS AND METHODS We report seven cases from our angiologic out-patient clinic. RESULTS The patients were asymptomatic between manifestations. The conditon was nevertheless reason for a referral. CONCLUSIONS We stress the need for greater awareness among clinicians of the harmlessness of the condition in order to avoid misdiagnoses and dispensable diagnostic procedures.
