Fibrous histiocytoma is a benign tumour composed of a mixture of fibroblastic and histiocytic cells. Based on the location of this tumour, fibrous histiocytoma are usually divided into cutaneous types and those involving deep tissues. These lesions most often arise on the skin, but may rarely occur in soft deep tissues. The diagnosis of fibrous histiocytoma may be clinically difficult when the ...

Benign fibrous histiocytoma or dermatofibroma is one of the most common types of benign, cutaneous, soft tissue tumors, most often found in the middle-aged adults. The diagnosis of dermatofibroma/benign fibrous histiocytoma is usually straightforward if the typical morphological features are present. However, some diagnostic difficulties may arise when one is dealing with some unusual morpholog...

A benign fibrous histiocytoma with primary site of origin in the parietal bone has not yet been reported in the literature. We report here a case concerning a 12-year-old girl with a 14-month history of an enlarging parietal bone mass. The tumor was excised after removal of the cortical bone and resection of the tumor surrounding the cortical bone erosion using pre-plasticity titanium repair. B...

Primary benign fibrous histiocytoma involving the central nervous system is an exceedingly rare tumor with most cases originating from the dura or parenchymal tissue. Diagnosis of primary benign fibrous histiocytoma is difficult due to its confusing histopathological characteristics. Two cases of primary intracranial benign fibrous histiocytoma mimicking parasagittal meningioma are presented in...

We report a case of benign fibrous Histiocytoma of the left tenth rib in a 40-year-old man. CT revealed an expanding lesion with calcification. An open biopsy of the lesion was performed and subsequently wide surgical resection of the left 10th rib was performed. Histological diagnosis was consistent with benign fibrous Histiocytoma of the rib.

Aneurysmal benign fibrous histiocytoma is an uncommon pathologic variant of dermatofibroma. In addition to the features of a typical dermatofibroma, it has large cleft-like or cavernous blood-filled spaces with numerous hemosiderin pigments. It should be differentiated from angiomatoid malignant fibrous histiocytoma, malignant melanoma, and vascular tumors such as Kaposi's sarcoma and angiosarc...

Fibrous histiocytoma is a benign soft tissue tumour arising as a fibrous mass everywhere in the human body. The involvement of the oral cavity is rare. We report two cases of benign fibrous histiocytoma that localized in the oral cavity. The clinical and histological features of the lesion are reported. Finally, a literature revision of this pathology at the level of the oral cavity is reported.
