Achenbach syndrome: a benign cause of blue finger illustrated by a case report
Abstract
Achenbach syndrome, or paroxysmal finger hematoma, is a benign vascular condition characterized by the sudden onset of pain, swelling, and bluish discoloration of the digits.Although self-limited, its dramatic presentation often leads to unnecessary investigations to exclude ischemic or thrombotic disease.We present a case of a 48-year-old female with acute-onset discoloration of the third finger and full spontaneous resolution within 1 week, illustrating the importance of recognizing this frequently underdiagnosed syndrome.
