BENIGN FIBROUS HISTIOCYTOMA OF THE HAND: A CASE REPORT AND LITERATURE REVIEW

Abstract

Benign fibrous histiocytoma (BFH) of the bone is a rare benign lesion characterised by the presence of fibroblasts and histiocytes. Fibrohistocytic lesions involving bone with identical histological appearances are common during childhood such as fibrous cortical defect. However, BFH is very rare and can only be differentially diagnosed with its presentation, localisation and radiologic features. Here we describe a 33-year-old man with BFH in a rare location, a phalanx. To our knowledge this is the second reported case of a BFH involving the proximal phalanx of the thumb in an adult. We report clinical, radiologic and histological findings of the case and briefly review the literature on the subject.
