Background This paper is aimed at studying the therapeutic effects of in situ replantation of alcohol-devitalized bone segments to treat malignant bone tumors of the knee joint. Methods We retrospectively analyzed clinical data for 45 patients from January 2013 to January 2016 who underwent replantation following alcohol-devitalization of bone segments and 40 who underwent prosthesis implanta...

primary malignant neoplasms of the pericardium are rare and are predominantly mesotheliomas, followed by benign localized fibrous mesothelioma, malignant fibrosarcoma, angiosarcoma and benign and malignant teratomas. 1 this article concerns an atypical presentation of this malignant tumor with symptoms and signs of pericardial effusion. this unusual feature was complete encasement of the heart ...

introduction: thermal ablation by microwave (mwa) has proven efficacy in treatment of primary and metastatic cancers. soft tissue tumors could be ablated completely using mwa. however, bony tissue metastasis particularly spinal vertebral metastasis ablation has not reported yet. case presentation: a 50 year old male patient with primary diagnosed colon cancer undergone surgical resection of tum...

The author reports a patient with a malignant phyllodes breast tumor, who then had a ten-year disease free interval before she developed a left pelvic bone metastasis and soft tissue invasion. Cross-sectional and radionuclide imaging of its musculoskeletal metastasis is presented. Literature concerning bone metastasis from phyllodes tumor is also briefly reviewed and discussed, along with its e...

desmoplastic fibroma (df) is a rare and locally aggressive intraosseous tumor with unknown etiology. the mandible is the common site of involvement in the maxillofacial region. however, it is believed that df can arise in any bone of the body. a wide age distribution has been reported for df occurrence, extending from birth to the sixth decade of life, with a peak incidence at 10 to 19 years of...

An 87 year-old white female presented with a two-year history of intermittent discomfort in her left foot. PET-CT identified intense18F-fluorodeoxyglucose (FDG) uptake corresponding to the lesion. Histology of a fine needle aspiration and open biopsy were consistent with a benign giant cell tumor (GCT) of the bone. GCT of bone is an uncommon primary tumor typically presenting as a benign solita...

Early and accurate detection of bone tumors and their staging are important since some of them are highly malignant. Intraoperative pathological consultation in bone tumors and tumor-like conditions is quite complex; however, it allows improvement in prognosis and limb salvage. Present study was conducted on 52 patients who underwent surgical procedure after clinical and radiological diagnosis ...

Malignant gliomas manifest frequent tumor recurrence after surgical resection and/or other treatment because of their nature of invasiveness and dissemination. The recognized brain tumor-tracking property of neural progenitor/stem cells opened the possibility of targeting malignant brain tumors using neural progenitor/stem cells. We and others have previously shown that fetal neural progenitor/...

neurofibromatosis type 2 is an inherited disease. the main manifestation of the disease is the development of symmetric, non-malignant brain tumors in the region of the cranial nerve viii usually as schwannoma. we report here a 20-year-old woman with primary intracranial malignant nerve sheath tumor located in the left cerebellopontine angle. histologically, the tumor showed malignant spindle c...
