THE SPECTRUM OF NORMOLIPEMIC PLANE XANTHOMA

Normolipemic plane xanthoma (NPX) is a well-characterized clinicopatho logic entity distinct from necrobiotic xanthogranuloma (NXG). We prese nt the case of a patient with the classic clinical course of NPX but w ith many histologic features in common with NXG, namely, multinucleate d lipophages, cholesterol clefts, and degeneration of collagen with as sociated cellular necrosis (necrobiosis). We suggest that NPX and NXG represent part of a spectrum of xanthomatous dermal reactions associat ed with paraproteinemias and may be more closely related than previous ly recognized.
