Osteofibrous dysplasia is a benign fibro-osseous lesion of bone which is most commonly occurred in cortical bone of anterior mid-shaft of the tibia of infancy and childhood. This study reported a case of osteofibrous dysplasia arising in the humerus of adult, resulting in good prognosis after a surgical treatment. A 34-year-old male had felt left upper arm pain and was suspected as having a bone tumor at the humeral shaft by X-ray pictures. Read More

Background: Periostin is a matricellular protein that is expressed in bone and joint tissues. To determine the expression of periostin in primary bone tumours and to assess whether it plays a role in tumour progression, we carried out immunohistochemistry and ELISA for periostin in a range of neoplastic and non-neoplastic bone and joint lesions.

Methods: 140 formalin-fixed paraffin-embedded sections of bone tumours and tumour-like lesions were stained by an indirect immunoperoxidase technique with a polyclonal anti-periostin antibody. Read More

Case: A 38-year-old man presented with multifocal, partially confluent osteolytic lesions in the proximal dia-meta-epiphyseal region of the proximal aspect of the left tibia, which had been found incidentally when a radiograph was made after a rotational knee injury. When the results of a percutaneous core needle biopsy proved inconclusive, an open biopsy was performed. Osteofibrous dysplasia (OFD) with scattered groups of plump cells with a rhabdoid phenotype, shown to express both vimentin and pan-cytokeratin, was found. Read More

Background: The proposed association between osteofibrous dysplasia and adamantinoma has led some to advocate resection of the entire lesion, which can require major subsequent reconstruction. However, this link remains unproven and there is some support in more recent literature for a less aggressive approach. This study aims to describe our experience managing pediatric tibial osteofibrous dysplasia with such an approach and to report functional outcomes in children treated thus. Read More

The periosteum contributes to bone repair and maintenance of cortical bone mass. In contrast to the understanding of bone development within the epiphyseal growth plate, factors that regulate periosteal osteogenesis have not been studied as intensively. Osteofibrous dysplasia (OFD) is a congenital disorder of osteogenesis and is typically sporadic and characterized by radiolucent lesions affecting the cortical bone immediately under the periosteum of the tibia and fibula.

We report a case of a very rarely seen osteofibrous dysplasia-like adamantinoma (OFDLA) of the lower leg in a 3-month-old male infant, making it the youngest case in the literature. OFDLA is typically regarded as a benign lesion; however, due to its convertibility into classical adamantinoma, it is recommended to evaluate it as a pre-malignant lesion. After OFDLA diagnosis with biopsy, our case underwent surgical resection and reconstruction with a large allograft. Read More

Diagnostic problems attending intraosseous and parosteal pseudoneoplastic lesions can be radiographic, or histological, or both. Proliferations in this category may contain cellular fibro-osseous or chondro-osseous tissues that are difficult to separate microscopically from those seen in various true neoplasms of the bones. This review considers the clinicopathologic features of fibrous dysplasia, benign fibro-osseous lesions of the jawbones, osteofibrous dysplasia, metaphyseal fibrous defect, giant-cell reparative granuloma, "brown tumor" of hyperparathyroidism, synovial chondrometaplasia, aneurysmal bone cyst, tumefactive chronic osteomyelitis, proliferative Paget disease, and polyvinylpyrrolidone storage disease of bone.

Parosteal osteosarcoma is a surface-based osteosarcoma that often exhibits deceptively bland cytologic features, hindering diagnosis in small biopsies or when correlative radiologic imaging is not readily available. A number of benign and malignant fibro-osseous lesions, including fibrous dysplasia (FD) and low-grade central osteosarcoma, fall within the morphologic differential diagnosis of parosteal osteosarcoma. Somatic mutations in GNAS, encoding the α-subunit of the heterotrimeric G protein complex (Gsα), occur in FD and McCune-Albright syndrome but have not been reported in parosteal osteosarcoma.

Objective: The aim of this study was to describe MR findings of osteofibrous dysplasia.

Materials And Methods: MR images of 24 pathologically proven osteofibrous dysplasia cases were retrospectively analyzed for a signal intensity of the lesion, presence of intralesional fat signal, internal hypointense band, multilocular appearance, cortical expansion, intramedullary extension, cystic area, cortical breakage and extraosseous extension, abnormal signal from the adjacent bone marrow and soft tissue and patterns of contrast enhancement.

Fibro-osseous lesions of the bone are well-recognized primary bone tumours. However, given the degree of overlap of imaging findings and variation in management of various sub-types, it is a widely accepted practice to perform a biopsy to obtain histopathological confirmation of the diagnosis. The following is a summary of the epidemiology, clinicopathological features, and review of the imaging features of fibro-osseous lesions, including osteofibrous dysplasia, osteofibrous dysplasia-like adamantinoma, adamantinoma, and lesions that closely mimic them.

Dentin matrix protein 1 (DMP-1) is highly expressed by osteocytes and is a non-collagenous matrix protein found in dentin and bone. In this study, we determined the expression of DMP-1 in mature and immature human bone and examined whether DMP-1 is useful in distinguishing osteoid/bone-forming tumours from other primary and secondary bone tumours. DMP-1 expression was immunohistochemically determined in paraffin sections of a wide range of benign and malignant primary bone tumours and tumour-like lesions (n = 353). Read More

Adamantinoma of long bones and osteofibrous dysplasia are rare, osteolytic primary bone tumours of uncertain origin containing areas of fibrous and fibro-osseous proliferation. We investigated the nature of the stromal cells in adamantinoma of long bones and osteofibrous dysplasia, and determined cellular and molecular mechanisms of osteolysis in these tumours. Cell culture, molecular (RT-PCR, western blot) and immunohistochemical studies on cases of adamantinoma of long bones and of osteofibrous dysplasia were undertaken to determine the expression of epithelial, osteoblast and osteoclast markers.
