Two Unusual Cases of Discoid Lupus Erythematosus Associated With Xanthomatized Macrophages.

We present 2 patients with chronic discoid lupus erythematosus (LE) associated with xanthomatized macrophages on light microscopic findings. Skin biopsies revealed hyperkeratotic and atrophic epidermis, vacuolar degeneration of the dermal-epidermal junction, thickened basement membrane, follicular plugging, and perivascular and perifollicular lymphohistiocytic infiltrate. Notably, large collections of lipid-laden histiocytes were observed within the subjacent dermis.
