Systemic juvenile xanthogranuloma (JXG) is a rare histiocytic disorder in which disease extends beyond the skin to involve 2 or more visceral organs. This multi-organ presentation places the case outside routine observation and requires a deliberate, structured therapeutic strategy.
For systemic JXG with multi-organ involvement, management may include surgical intervention or systemic therapeutic strategies. Which approach is appropriate — and in what sequence — depends on clinical factors specified in the full protocol.
Systemic JXG is a rare histiocytic disorder that usually manifests as multiple cutaneous and/or subcutaneous nodules and involvement of 2 or more visceral organs.
Options described include surgical resection, radiation therapy and/or chemotherapy with prednisone and vinblastine regimens used in LCH, or, for refractory cases, cytarabine and 2-chlorodeoxyadenosine.
