Multiple Adult Xanthogranulomas Associated With Cutaneous Lymphoid Hyperplasia and Lupus Erythematosus.
A 50-year-old woman presented to our clinic for evaluation of numerous recurrent, pruritic papules on her upper extremities. She reported a 2- to 3-year history of up to eight unique lesions on the bilateral upper arms that would initially appear as firm papules before gradually softening and flattening out, leaving residual pink macules (Figure 1A). Her medical history was notable for mild hyperlipidemia. On presentation, she had several erythematous papules with overlying telangiectasias scattered throughout her bilateral upper arms. One lesion of concern over the left deltoid had been present for 5 months without signs of regression (Figure 1B). Pathology of this and a similar lesion showed histiocytes forming Touton giant cells with foamy cytoplasm consistent with a xanthogranuloma (AXG). Results from immunoperoxidase stains were negative for factor XIIIa and CD1a, diffusely positive for CD68, and focally positive for S100 (Figure 2).
