Achenbach Syndrome: Minor Traumatic Injury as a Possible Etiology

Achenbach syndrome is a rare cause of acute bluish discoloration and swelling of one or more digits, of unknown etiology. The condition is self-limited and benign but is worrisome for both patients and healthcare providers due to its emulation of peripheral ischemia. Familiarity with the clinical features of Achenbach syndrome allows for rapid diagnosis and mitigation of costs and anxiety associated with unnecessary testing and referrals. We report a case of Achenbach syndrome associated with a puncture wound, which supports a traumatic etiology for this condition.
