Achenbach Syndrome: Case Report and Discussion

Achenbach syndrome is a rare, benign, self-limiting condition characterized by spontaneous, recurrent bruising of the digits without evidence of systemic disease or predisposing factors. We report a middle-aged Caucasian female that presented to the outpatient clinic with spontaneous bruising on the dorsal aspect of her left first metacarpal. Diagnosis of Achenbach syndrome was made through history and physical examination findings, and the patient was discharged with instructions to follow up as needed. It is important for providers to consider Achenbach syndrome to reassure patients and prevent an expensive or invasive workup.
