[Bilateral adult periocular xanthogranuloma].

PATIENT

A 62-year-old woman was evaluated for a bilateral subconjunctival mass that had been present for 6 months. With magnetic resonance imaging the lesion could not be delineated form the lacrimal glands. A biopsy was performed and histologic examination exhibited a xanthogranulomatous lesion with multiple giant-cells of the Touton type. The differential diagnosis of the adult xanthogranuloma is Erdheim-Chester disease, necrobiotic granuloma, xanthoma, Langerhans histiocytosis, and Rosai-Dorfman syndrome.

CONCLUSION

Hyperlipemia should be excluded, in addition, in the presence of necrobiosis, paraproteinemia.
