PURPOSE: To report a case in an adult of xanthogranuloma of the iris that clinically simulated iris melanoma. DESIGN: Observational case report. METHODS: Clinical and histopathologic examination of iris mass obtained from a 77-year-old white woman. RESULTS: High-frequency ultrasonography of the right eye revealed a small, echodense lesion involving the iris root. The mass revealed histopathologic features identical to juvenile xanthogranuloma (JXG), including histiocytes and lymphocytes mixed with multinucleated giant cells, and eosinophilic leukocytes. The histiocytes stained positive for CD68, CD45, and factor XIIIa and negative for S-100 and CD1a. CONCLUSIONS: Xanthogranuloma of the iris can occur in elderly patients. Such lesions should be considered in the differential diagnosis of iris melanoma.
