Primary benign fibrous histiocytoma (BFH) at the skull is extremely rare. Here we report a case of a 22-year-old man presented with a 1-year history of progressive enlargement subcutaneous mass on the right side of the fronto-temporo-parietal region without symptoms. The tumor was radical resected through craniotomy and the bone defect was repaired by pre-plasticity titanium mesh. Histopatholog...

Fibromyxoma of bone is a rare benign tumor of fibrous tissue origin. The typical location is the jaws. Sporadic extragnathic cases have been reported, but fibromyxoma of the spine has not been reported. The histological appearance of fibromyxoma is benign and includes abundant extracellular fibrous and myxoid stroma with varying amounts of calcification and ossification. Myxoid changes are usua...

UNLABELLED 18F-fluoride PET/CT was performed on 44 oncologic patients to evaluate its diagnostic accuracy in assessing malignant osseous involvement and in differentiating malignant from benign bone lesions. METHODS (18)F-fluoride PET and (18)F-fluoride PET/CT were interpreted separately. Lesions showing increased (18)F-fluoride uptake were categorized as malignant, benign, or inconclusive. T...

The upper-middle tibia is the mult iple growth section of benign and malignant neoplasm, which is easy to result in bone defect after tumorectomy and it is a serious problem in orthopaedics. We reported a case about a huge benign or potential malignant tumor( giant cell tumor of bone) in upper-middle tibia and contrasted the advantage between the jade prosthesis and the allograft. Initially, th...

Giant cell tumor is a benign primary bone tumor. The phalangeal localization rare. It distinguished from other locations by the local aggressiveness of and high rate recurrence. We report one case 25-year-old right-handed nurse with no reported pathological history who complained about an ulcero-budding mass right little finger evolving year ago. She would have initially consulted bonesetter ta...

Giant cell tumor of the bone (GCTOB) is a relatively uncommon tumor of the bone. It is characterized by the presence of multinucleated giant cells. Giant-cell tumor of the bone accounts for 4-5% of primary bone tumors and ∼20% of benign bone tumors. Giant cell tumors of the hand are rare, accounting for only 2-4% of all giant cell tumors. Giant cell tumor (GCT) of the bones of the hand has some...

Chondroblastoma is a rare, benign bone tumor that represents 1-2% of all primary bone tumors. Denosumab, a monoclonal antibody, has been demonstrated to inhibit the growth of giant cell tumors. We report a case of recurrent chondroblastoma of the squamous temporal bone that is currently suppressed with denosumab.

ally involves the metaphysis and epiphysis of long bones. Although the spine is the fourth leading location of GCT, most of these lesions occur in the sacrum, followed by the thoracic, cervical and lumbar vertebrae (1). GCT of bone is a benign, but potentially aggressive lesion that shows local recurrence and metastases. Metastatic lung disease rarely originates from a benign tumor, but this ca...

osteoma is a benign, slow-growing osteogenic tumor that sometimes arises from the craniomaxillofacial region, such as the sinus, temporal or jaw bones. osteoma consists of compact or cancellous bone that may be peripheral, central or extraskeletal type. peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. peripheral osteoma of the mandible...

Desmoplastic fibroma of bone is a rare myofibroblastic tumor, locally aggressive, benign lesion that histologically resembles a desmoid tumor of the soft-tissue. It was initially described in 1958 by Jaffe, who separated it as a distinct entity from other intraosseous fibrous tumors. This tumor constitutes <1% of bone tumors and about 0.3% of all benign osseous tumors and it usually involves th...
