Abstract

We report a case of ulcerated atypical Spitz nevi that demonstrated a yellow to light orange background under dermoscopy, which can be seen in juvenile xanthogranuloma (JXG) and is referred to as the "setting sun" appearance. This yellow to orange appearance was due to serous crusting and not histiocytic infiltration, which is seen in JXG. This case highlights overlapping dermatoscopic features between the two skin lesions and polymorphous vascular structures, which are unique to atypical Spitz nevi.
