PURPOSE The proximal femur is one of the most common locations for benign bone tumors and tumor like conditions. We describe the clinical outcomes of the surgical treatment of benign lesions of the proximal femur including femoral neck using compression hip screw and synthetic bone graft. METHODS Thirteen patients with benign bone tumors or tumor like conditions of the proximal femur includin...

Chondromyxoid fibroma (CMF) is a rare, benign cartilaginous tumor, comprising less than 1% of primary bone tumors, and usually occurs in the metaphysis of a long tubular bone around the knee. We report a rare case of CMF of the rib. The patient was a 25-year-old man who visited the hospital for left upper back pain. Roentgenography revealed an 8-cm mass in the left upper lung field; computed to...

Background/Aim: The purpose of this study was to investigate whether bone morphogenetic protein (BMP)-4 expression differs according the presence calcification in papillary thyroid carcinoma and if BMP-4 are associated with metastasis carcinoma.Methods: We performed using paraffin-embedded tissues 55 patients who underwent thyroidectomy Kosin University Gospel Hospital. Of those cases, 36 were ...

objective(s): this study aimed to evaluate the role of pretreatment suvmax and volumetric fdg positron emission tomography (pet) parameters in the differentiation between benign and malignant mediastinal tumors. in addition, we investigated whether pretreatment suvmax and volumetric fdg-pet parameters could distinguish thymomas from thymic carcinomas, and low-risk from high-risk thymomas.method...

Osteoid osteoma is a benign primary bone tumor containing a small region of abnormal osteoid with osteoblasts and variable surrounding reactive bone. Osteoid osteoma accounts for approximately 11% of all benign tumors.1 The majority of osteoid osteomas are monofocal with a single nidus. The orthopedic and radiology literature is scattered with several case reports of multicentric osteoid osteom...

Brown tumors are focal bone lesions, caused by increased osteoclastic activity and fibroblastic proliferation, encountered in patients with uncontrolled hyperparathyroidism (HPT). They can be located in any part of the skeleton, but are most frequently encountered in the ribs, clavicles, extremities, and pelvic girdle. Clinically significant lesions in the craniofacial bones are rare Brown tumo...

this study aimed to investigate the frequency of varicella zoster virus (vzv) in benign and malignant breast tumors. a total of 24 carcinomas and 24 fibroadenomas paraffin embedded tumoral tissue samples were obtained from the pathology sections of toos and firoozgar hospitals in tehran, iran. all samples were collected from patients from june 2011 to february 2012. dna was extracted from all s...

The treatment of benign bone tumors (BBT) and tumor-like bone lesions (TBL) has observed the introduction of new drugs, such as intravenous bisphosphonates, which have ossified bone lesions caused by fibrous dysplasia. Aneurismal bone cyst has been treated with sclerosing agents by percutaneous injection, yielding good results. Adjuvants allow joint salvage, maintenance of movements and functio...

PURPOSE To establish guidelines for interpretation of orbital imaging by magnetic resonance imaging (MRI) and/or computed tomography (CT), and to apply these guidelines and examine their predictive value in 131 patients with biopsy-proven orbital tumors. DESIGN Prospective evaluation of imaging studies. PARTICIPANTS Imaging studies (CT and/or MRI) from 131 cases with biopsy-proven orbital t...
