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).
