Overview
Juvenile xanthogranuloma (JXG) is a benign histiocytic disorder predominantly affecting children, often involving the skin but potentially impacting ocular structures, including the choroid plexus, leading to complications such as hyphaemia and glaucoma 12.Diagnosis
Clinical Presentation: Multiple skin lesions, especially in younger children (≤2 years) 1.
Ophthalmologic Evaluation: Essential for detecting intraocular involvement; includes slit-lamp examination and possibly imaging under anesthesia 12.
Imaging: Ultrasound and CT may be useful for detecting extraskin manifestations like renal involvement 3.
Laboratory Tests: Not typically specific; may include complete blood count to rule out associated conditions like sickle cell disease or leukemia 2.Management
Monitoring: Regular ophthalmologic screening for children with multiple skin lesions or newly diagnosed JXG 1.
Surgical Intervention: May be required for severe intraocular complications such as hyphaemia or glaucoma 2.
Medical Management: No specific drug treatments mentioned for choroid plexus involvement; supportive care and management of complications 123.Special Populations
Pediatrics: Increased risk in younger children with multiple skin lesions; targeted screening recommended 1.
Comorbidities: Presence of conditions like sickle cell disease or leukemia may complicate diagnosis and management 2.Key Recommendations
Ophthalmologic Screening: Perform regular ophthalmologic evaluations in children with cutaneous JXG, particularly those ≤2 years old with multiple lesions or recent diagnosis (Evidence: Moderate) 1.
Early Detection: Focus surveillance efforts on high-risk patients to prevent complications like hyphaemia and glaucoma (Evidence: Moderate) 12.
Referral Practices: Ensure consistent referral to ophthalmologists for suspected intraocular involvement, despite variability in current practices (Evidence: Expert opinion) 1.References
