Juvenile Xanthogranuloma (JXG) is a benign "histiocytic" disorder typically characterized by orange-yellow skin nodules. However, it is the most common cause of spontaneous "hyphema" (bleeding in the eye) in children.
read more about xanthogranuloma ...In the eye, JXG usually manifests as a small, vascularized yellowish growth on the iris. Because these lesions are fragile, they can bleed easily into the anterior chamber of the eye.
Recurrent bleeding from an iris xanthogranuloma can clog the eye's drainage system, leading to secondary "glaucoma" and potential vision loss if not managed promptly.
Diagnosis is often clinical, based on the presence of skin lesions. If the eye is involved without skin signs, an aqueous tap or iris biopsy may be necessary to confirm the diagnosis.
Treatment typically involves topical or systemic corticosteroids to shrink the lesion. In resistant cases, low-dose radiation or surgical excision may be considered.
No, JXG is a benign (non-cancerous) condition, although its location in the eye can cause serious complications.
Many skin lesions regress spontaneously over several years, but ocular lesions usually require active medical treatment to prevent bleeding.
It most commonly appears in infants and children under the age of two, though adult cases are occasionally reported.
