Background: It has been reported that sternal neoplasms are a rare disease, accounting for about 1% of primary bone neoplasms, which 60% malignancy, mostly occurring in the manubrium sternum. Case presentation: We reviewed 77-year-old man with solitary plasmacytoma stalk presenting pain anterior chest wall by examining preoperative diagnosis malignant tumor. performed extensive tumor resection ...

OBJECTIVE To develop an accurate method for performing histopathologic analysis for a full cross-section of cortical bone within 2 to 3 hours. METHODS Microwave technology was used to augment and to more rapidly perform fixation and decalcification of cortical bone. RESULTS Using the methods described, slides suitable for histopathologic analyses regarding the presence or absence of maligna...

OBJECTIVE To analyze different fluid-fluid level features between benign and malignant bone tumors on magnetic resonance imaging (MRI). MATERIALS AND METHODS This study was approved by the hospital ethics committee. We retrospectively analyzed 47 patients diagnosed with benign (n = 29) or malignant (n = 18) bone tumors demonstrated by biopsy/surgical resection and who showed the intratumoral ...

Osteosarcoma is the most frequent malignant bone tumor with a peak incidence in the second and third decades of life. Diagnosis of patients with osteosarcoma is limited to clinico-pathological parameters whereas molecular markers of tumor initiation and promotion have not yet been identified. We aimed to study the expression of the anti-apoptotic survivin gene in osteosarcoma specimens. A total...

background: massive bone allograft is an option in cases of limb preservation and reconstruction after massive benign and malignant bone tumor resection. the purpose of this study was to analyze the outcome of these procedures at imam reza hospital, mashhad university of medical sciences. methods: in this study, 113 cases have been presented. eleven cases were excluded (patients has a traumatic...

osteosarcoma is a relatively uncommon malignancy however, it is the most common form of primary malignant bone tumors in human. diagnosis and prognosis of patients with osteosarcoma is limited to clinico-radiopathological parameters, whereas molecular markers of tumor aggression have been poorly identified. survivin, an inhibitor of apoptosis (iap), is unique for its expression in human tumors ...

Aims At the histological level, the differential diagnosis of osteoblastic bone tumors is characterized by several problems that cannot be solved by conventional histological methods, including immunohistology. Differentiating aneurysmal bone cyst from telangiectatic osteosarcoma or giant cell tumor from giant cell-containing highly malignant osteosarcoma are only two examples reflecting the co...

An ameloblastic fibroma (AF) is a proliferative mixed tumor which includes components of both odontogenic epithelium and mesenchymal tissue. It relatively rare neoplasm, accounting for approximately only 1.5－4.5% tumors. This case report describes an AF that occurred in the mandibular anterior tooth region 9-year-old girl who presented with chief complaint swelling left region. Intraoral examin...

In this study characteristics and distribution of primary bone and soft tissue tumors which were operated in Inonu University Turgut Ozal Medical Center Department of Orthopaedics and Traumatology between January 2000 and December 2016 and comparison with the literature is aimed. Our study is retrospective and descriptive and 710 patients [275 M, 435 F, mean age: 30,67 (1-92)] who hospitalized ...

Giant cell tumor of soft parts (GCtSP) is an extremely rare soft tissue tumor that resembles its counterpart in bone. It is considered a soft tissue counterpart of giant cell tumor of the bone (1-3). The tumor is composed of an admixture of osteoclast-like multinucleated giant cells and mononuclear stromal cells (3,4). The lesion was first described in 1972 by Salm and Sissons and Guccion and e...
