Purpose: To describe a clinical case of corneoscleral xanthogranuloma, a rare manifestation of juvenile xanthogranuloma, and xanthoma disseminatum, which responded well to chemotherapy. Methods: Interventional case report and literature search. Results: A 9-year-old female patient with a disseminated disease showed complete regression of her corneoscleral xanthogranuloma with methotrexate and azathioprine therapy. Conclusion: Since they are potentially blinding, corneoscleral xanthogranulomas are commonly surgically excised. While surgical resection has been widely advocated in the literature, immunosuppressive therapy alone may be a pertinent management line of corneoscleral xanthogranuloma, especially with systemic involvement.
