Endoscopic Resection of a T-Shaped Benign Fibrous Histiocytoma at the Skull Base in a Pediatric Patient

Abstract

Background: Benign fibrous histiocytoma (BFH) is a benign tumor composed of cells with characteristics of histiocytes and with fibroblastic components. BFHs are rare lesions, especially in the skull base. Clinical Presentation: Here, the authors report the case of a 9-year-old girl presented with reduced binocular vision for 2 months. The computerized tomography (CT) of the tumor appearance was high-density annular sclerosis. The tumor was removed via nasal endoscopic approach. Final pathologic diagnosis was benign fibrous histiocytoma. The post-operative period was uneventful after 8 months, and the visual acuity was improved to some extent. Discussion and Conclusion: This is the first case of BFH in a pediatric patient that was removed by endoscope. For similar case, endoscopic resection might be the first choice, including pediatric patient. Moreover, the CT feature and literature review may provide further insight into the diagnosis and management.
