Benign fibrous histiocytoma involving the skull: a case report and literature review / 南方医科大学学报

ABSTRACT

Benign fibrous histiocytomas (BFH) represent a rare group of tumors with a common origin from the tissue histiocytes, often causing pain and space-occupying effect. BFH of bone causes diagnostic difficulties due to its atypical clinical symptoms, radiographic features and cytological characteristics, which can be easily confused with other benign lesions such as non-ossifying fibroma (NOF), giant cell tumor (GCT), and fibrous dysplasia. The lesions are prone to relapse, and the patients often show poor response to radiotherapy and chemotherapy, therefore radical lesion resection should be the therapeutic target of this disease. This paper reported a case of BFH involving the skull and reviewed the associated literatures.
