Calcinosis cutis lesions are hard, whitish, and may extrude chalky material, unlike the softer, yellowish, lipid-filled papules of eruptive xanthomas.

Papular GA can appear as numerous skin-colored or reddish papules, but they lack the distinct yellow color of xanthomas.
This is a benign proliferation of histiocytes presenting as crops of reddish-brown papules that are clinically and histologically distinct from lipid-laden xanthomas.
These are deposits of uric acid, often over joints, and lack the characteristic yellow hue of xanthomas.
The cutaneous lesions of LCH are typically reddish-brown, scaly papules, often in a seborrheic distribution, and are composed of Langerhans cells, not foam cells.

This is a category of disorders; specific entities like juvenile xanthogranuloma present as a reddish-yellow nodule, but eruptive xanthomas are defined by their link to hypertriglyceridemia.
