BACKGROUND Juvenile xanthogranuloma is a benign, self-limiting cutaneous disorder most commonly encountered during infancy. Approximately 10% of cases may develop ocular or adnexal involvement, most commonly in the iris. METHODS We review clinical and morphological features of four cases of iris juvenile xanthogranuloma that reflect the diagnostic and therapeutic spectrum. RESULTS Tissue diagnosis was confirmed in all cases; in one case, the disease was diagnosed with a skin biopsy and treated with local and systemic steroids, and its persistence in the iris was confirmed with a second tissue specimen obtained five months after systemic steroid treatment. CONCLUSIONS The diagnosis and treatment of juvenile xanthogranuloma may be straightforward, particularly in cases when the ocular lesion receives early attention and responds well to topical steroids, and when there is no hyphema. However, in other instances, this entity may be difficult to manage and may necessitate iris biopsy for diagnosis and radiation therapy for treatment.

D007429	Intraocular Pressure	The pressure of the fluids in the eye.	Ocular Tension,Intraocular Pressures,Ocular Tensions,Pressure, Intraocular,Pressures, Intraocular,Tension, Ocular,Tensions, Ocular
D007498	Iris	The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.
D007499	Iris Diseases	Diseases, dysfunctions, or disorders of or located in the iris.	Disease, Iris,Diseases, Iris,Iris Disease

D011882	Radiotherapy, High-Energy	Radiotherapy using high-energy (megavolt or higher) ionizing radiation. Types of radiation include gamma rays, produced by a radioisotope within a teletherapy unit; x-rays, electrons, protons, alpha particles (helium ions) and heavy charged ions, produced by particle acceleration; and neutrons and pi-mesons (pions), produced as secondary particles following bombardment of a target with a primary particle.

D005938	Glucocorticoids	A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system.

D006644	Histiocytes	Macrophages found in the TISSUES, as opposed to those found in the blood (MONOCYTES) or serous cavities (SEROUS MEMBRANE).	Histiocyte

D000287	Administration, Topical	The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.
