Abstract
OBJECTIVE
The aim of the present study was to carry out a systematic review of available data regarding case reports and case series of oral and maxillofacial benign fibrous histiocytoma (BFH).
STUDY DESIGN
A search strategy was performed using the PubMed, Web of Science, Scopus, and EMBASE electronic databases.
RESULTS
Male individuals (56.89%) were more affected, with a mean age of 34.55 ± 20 years. The buccal mucosa (20.33%) represented the most common site, with the clinical presentation of a painless (86.95%) nodule (98.03%). The clinical hypothesis of a fibroma was reported in most cases (31.57%). Radiographic presentation of intraosseous lesions showed multilocular radiolucent images (55.55%). Regarding the histopathologic features, the biphasic population of fibroblastic and histiocytic cells was seen in 21 cases (39.62%), and a spindle-shaped fibroblastic cell population organized into a storiform pattern was observed in 25 cases (47.16%). CD68 (n = 26) and vimentin (n = 25) showed immunoreactivity in all BFH cases in which they were used. All cases were treated with a surgical resection, and 8.10% recurred.
CONCLUSIONS
The current systematic review demonstrated that BFH represents a rare lesion that mainly affects the buccal mucosa of male individuals, and the treatment is mainly surgical with a good prognosis.
