Ocular Juvenile Xanthogranuloma With BRAF V600E Mutation in a Child.

The authors present a case of bilateral painless progressive proptosis. A diagnosis of ocular juvenile xanthogranuloma was made based on clinical manifestations, histopathology, and immunohistochemistrical staining. Genetic testing discovered the BRAF V600E mutation. This patient did not respond to standard chemotherapy; however, he demonstrated regression after anti-BRAF targeted therapy. .
