Tumor-like bony lesions are, by definition bony lesions, which can be clinically, radiologically and histologically mistaken for real bone tumors. This article presents the aneurysmal bone cyst (ABC), solitary bone cyst (SBC), fibrous dysplasia, osteofibrous dysplasia Campanacci and non-ossifying fibroma (NOF). Many tumor-like bony lesions are often incidental findings. Read More

Fibrous dysplasia is an unusual pathologic condition caused by abnormal bone metabolism. Temporal bone involvement is often seen, but it is uncommon to find fibrous dysplasia limited to the middle ear, especially originating in and confined to a single ossicle. Here we report a case of osteofibrous dysplasia limited exclusively to an ossicle (malleus) causing gradual conductive hearing loss, which recovered after eventual complete removal of the dysplastic area.

Osteofibrous dysplasia is a rare and benign nonneoplastic condition of unknown etiology in humans and mammals. An adult female cockatiel () was presented with the following problems: a soft tissue mass on the left frontal area of the head that extended over the left eye, anorexia, lethargy, and emaciation. Computed tomographic imaging and ultrasonography revealed a soft tissue opacity in the left cranial area of the head with multifocal heterogeneous opacities and foci of mineralization. Read More

Introduction: Amphiphysin 1 (AMPH-1) is involved in endocytosis, and its expression is upregulated in osteosarcoma compared with osteofibrous dysplasia.

Methods: We investigated the role of AMPH-1 in osteosarcoma cells via both gain-of-function and loss-of-function experiments.

Results: Knockdown of in osteosarcoma cells promoted cell cycle progression and cell proliferation and attenuated apoptosis. Read More

Osteosarcoma (OS) is the primary bone malignancy in children and adolescents, with a high incidence of lung metastasis and poor prognosis. Here, we report that growth hormone receptor (GHR) is overexpressed in OS samples compared with osteofibrous dysplasia. We subsequently demonstrated that GHR knockdown inhibited colony formation, promoted cell apoptosis and decreased the number of cells at G2/M phase in 143B and U2OS cells. Read More

Adamantinoma of the bone is a rare low-grade bony tumor that accounts for less than 1% of all primary bone tumors. On imaging, adamantinoma may be similar to other tumors such as osteofibrous dysplasia, for which the treatment protocol is completely different. Therefore, correct diagnosis and staging of adamantinoma ensures that the patient will undergo appropriate surgery. 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

Adamantinoma and osteofibrous dysplasia (OFD)-like adamantinoma are rare primary bone tumors that are predominantly confined to the tibia. These 2 entities show similarities in location, histology, and radiologic appearance; however, adamantinoma is malignant and therefore differentiating between these bone tumors is essential for optimal patient care. To elucidate their genomic and transcriptomic alteration profiles and expand their etiological mechanisms, whole exome sequencing (WES) and RNA sequencing (RNA-Seq) were conducted on adamantinoma and OFD-like adamantinoma tumors.

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.
