A 67-year-old woman presented to our clinic because she had developed spontaneous pain and purple discoloration of the fourth finger of her right hand that had started the previous day. She had experienced similar episodes previously, which were not related to cold exposure and had resolved spontaneously. She had no history of trauma and was not taking any medication. On examination, the finger showed mild swelling and a reddish-purple hematoma centered around the proximal interphalangeal joint (Fig. 1). The area was tender and she reported paresthesia. Blood tests showed a normal platelet count and found no abnormalities in the coagulation system.

The differential diagnosis includes acute ischemia, Raynaud's syndrome, acrocyanosis, Gardner-Diamond syndrome (psychogenic purpura), and chilblains; however, Achenbach's syndrome can be diagnosed based on a detailed medical history and the physical signs [
Clinicians should be familiar with Achenbach's syndrome in order to make a correct diagnosis so that they can reassure patients that it is not a serious condition and treat it conservatively.
