The first total vertebral involvement of benign fibrous histiocytoma: A case report and literature review

BACKGROUND: Benign fibrous histiocytoma (BFH) is a rare bone tumor, extremely seldom in the spine. METHODS: We present a 52-year-old patient diagnosed with a BFH in the thoracic spine treated with total en bloc spondylectomy. A review of the published literature was also conducted. RESULTS: Non-ossifying fibroma (NOF) and BFH are named as one tumor called NOF/BFH. A total of 20 spinal BFHs have been previously reported, mainly involving the posterior elements. We present a BFH with total vertebral involvement. Curettage and excision are the main treatment options with limited recurrence. CONCLUSIONS: This is the first total vertebral BFH up to now. Spinal BFH occupies rather low aggressiveness. With rather limited recurrence and malignant degeneration, surgical interventions seem enough for its management.
