Although the long-term outcome of localized extranodal marginal zone B-cell lymphoma of the ocular adnexa is good, optimal treatment remains a goal. The variation in rates of local and systemic relapse among treated stage 1E tumors suggests that critical factors affecting outcomes are not fully understood. Radiotherapy is the standard of care; at this time, the evidence is insufficient to recommend chemotherapy, immunotherapy, or antibiotics for initial treatment of extranodal marginal zone B-cell lymphoma localized to the ocular adnexa. Well-controlled comparative studies are needed.

We report a unique case of periocular nonnecrobiotic necrobiotic xanthogranuloma in a 52-year-old white woman with Sjögren syndrome who was subsequently found to have an immunoglobulin G paraproteinemia and coexisting small lymphocytic lymphoma. Therapy with fludarabine, cytoxan, and rituximab (FCR) resulted in a dramatic resolution of her sicca symptoms and periocular xanthogranulomas. This case further illustrates the association of hematolymphoid disorders with cutaneous xanthogranulomatous disease and the importance of additional appropriate laboratory and radiologic investigation for the accurate diagnosis of an underlying malignancy.
