| Abstract: | Deep “benign” fibrous histiocytoma(DBFH)is a rare benign fibrous tumour which most commonly arise in subcutaneous tissue. We report a 56-year-old female who presented with a painless nodule on her left arm for 4 years. Histopathology examination showed a solitary oval and well-defined borders subcutaneous tumour with fibrous pseudocapsule. The dimensions of tumour were about 1.8 cm×1.3 cm×0.6 cm, composed of bland ovoid to spindle cells arranged in a storiform pattern and with no atypia. Immunohistochemistry demonstrated CD34 positive, αSMA partially positive, and non-expression for Desmin, Stat6 and KP-1. Ki-67 presented a level of proliferation index of about 2%. The diagnosis of DBFH was made and the nodule was completely excised with no recurrence for 16 months. |
