Painful Blue Finger—Achenbach's Syndrome: Two Case Reports

INTRODUCTION: Herein, two cases of a rare, self resolving condition are described. Vascular surgeons are often called to see patients with spontaneous discolouration of extremities and digits. Often after extensive investigations no diagnosis can be ascertained and the condition resolves spontaneously. REPORT: Two cases are described here, which presented with spontaneous onset of this condition and after extensive testing no cause was ascertained. The condition resolved spontaneously. DISCUSSION: Achenbach's syndrome is a benign, self-limiting condition of unknown aetiology and clinicians should be aware of it to avoid unnecessary time consuming and expensive investigations.
