Necrobiosis lipoidica
LEGEND
Palisading (elongated histiocytes with nuclei aligned parallel to one another) is oriented parallel to the epidermis.
The epidermis may be normal, atrophic, or ulcerated.
Extensive necrobiosis extending into the hypodermis, with palisading histiocytes forming layered arrangements between zones of necrobiosis, resembling the appearance of lasagna.
