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.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
