case_images: Physical exam revealed several variously sized purpura, necrosis, erosion and ulcers located on her right arm and hand (Figure 1A and B).  CT angiography of the right upper limb showed a high origin of the radial artery, meanwhile both high originating radial artery and the anastomoses were tortuous and were of relatively small caliber (Figure 1E and F). Without any other specific treatment except tissue debridement during two weeks, her ulcers diminished and most of the purpuras fell off, leaving focal atrophic scars (Figure 1C and D).
