Summary
Juvenile xanthogranuloma is a rare condition that can affect spinal nerve roots. This case report details a unique instance of this tumor impacting the first sacral nerve root, causing significant pain.
Area of Science:
- Neurology
- Pathology
- Oncology
Background:
- Juvenile xanthogranuloma (JXG) is a rare, benign neoplastic proliferation of non-Langerhans cell histiocytes.
- While typically presenting in the skin or soft tissues, extraspinal JXG is uncommon.
- Spinal nerve root involvement by JXG has not been previously documented.
Observation:
- A patient presented with low back pain and sciatica, indicative of S1 nerve root irritation.
- Imaging studies, including CT and MRI, identified a mass originating from the right S1 nerve root.
- Surgical resection of the mass was performed for diagnosis and symptom relief.
Findings:
- Histopathological and immunocytochemical analysis confirmed the resected tumor as juvenile xanthogranuloma.
- This represents the first documented case of JXG affecting a spinal nerve root.
- The tumor's origin from the S1 nerve root was clearly established.
Implications:
- This finding expands the known spectrum of juvenile xanthogranuloma presentation.
- It highlights the importance of considering rare soft tissue tumors in the differential diagnosis of spinal nerve root masses.
- Further research may be warranted to understand the pathogenesis and optimal management of spinal JXG.
