Management of Uveitis and Scleritis in Necrobiotic Xanthogranuloma

Necrobiotic xanthogranuloma (NXG) is a chronic, progressive non-Langerhans histiocytic granulomatous disease. While case reports describing periorbital involvement of NXG are frequent, only a few case reports describing ocular involvement, such as scleritis and uveitis, exist. Herein, we present a case presenting initially as bilateral anterior and posterior scleritis, as well as a chronic bilateral granulomatous panuveitis, and discuss the immunosuppressant options that should be considered for this disease with protean manifestations.

[Disseminated necrobiotic xanthogranuloma]

Necrobiotic xanthogranuloma is a rare non-Langerhans-cell histiocytosis. A 62-year-old woman presented with yellowish erythematous plaques, nodules, and papules in the periorbital region and the extremities. She had a nodular tumor grown on the left upper lid that clinically resembled a keratoacanthoma. Histologically it was a xanthogranulomatous lesion. She suffered from monoclonal gammopathy of unknown significance of κ‑type. Treatment was realized with a combination of systemic dapsone/prednisolone and topical corticosteroids.
