Intraocular juvenile xanthogranuloma of the iris in an adult patient

Abstract

Purpose: Juvenile xanthogranuloma (JXG) is a rare histiocytic skin disease primarily of young children, which may also affect ocular structures and in particular the iris. Observations: This is a case report of a fifty-year-old patient without skin lesions showing a progressive decrease of visual acuity, iris vascularization and a yellowish iris tumor in the iridocorneal angle of his right eye. Treatment with topical and systemic prednisolone led to full recovery of visual acuity, tumor regression and restitutio ad integrum. Conclusions and importance: Although the juvenile xanthogranuloma is a very rare skin disease of young children, it may also affect the eye and in particular the iris in adult patients. There exists no standard treatment, the first-line therapy in most cases, however, is topical and systemic prednisolone application.
