There is no consensus on the optimal method of local control in Ewing's sarcoma (ES) of the mobile spine. Recent reports have suggested that en bloc resection may improve local control and survival. The authors therefore performed a systematic review to answer the following questions: (1) What is the outcome of en bloc resection for ES of the mobile spine with respect to local control and disea...
Introduction Proximal femur is the common site for localization of benign bone lesions, and the diagnosis is often delayed and potentially challenging due to their atypical presentations. Early diagnosis is difficult as intra-articular lesions often present with clinical and radiological features of inflammatory synovitis in the joint. Case Report Two patients of intra-articular osteoid osteo...
Osteosarcoma is the most common primary malignant bone tumor. The distal radius is a relatively common skeletal site for primary bone tumors, but not for osteosarcoma. It is difficult to treat Osteosarcoma of the distal radius; however, skeletal reconstruction and functional restoration following en bloc resection may be a promising technique. This report presents a 17-year-old male with osteos...
BACKGROUND Transurethral resection of bladder tumor (TURBT) is the standard approach to bladder tumors but suffers from several disadvantages. The aim of this study was to evaluate the safety and efficacy of a novel procedure of retrograde en bloc resection of bladder tumor (RERBT) with conventional monopolar resection electrode for the treatment of superficial bladder tumors. METHODS RERBT a...
Posterior mediastinal schwannomas are benign, slow growing nerve sheath tumors and rarely cause symptoms. We present a case of a 47-year-old man who presents with severe mid-back pain and dyspnea on exertion. Chest radiograph and computed topography revealed a large posterior mediastinum mass. Surgical resection required en bloc resection of a portion of the diaphragm, and wedge resection of th...
Parathyroid carcinoma is a rare disease in pediatric patients. We present a case of a 13-year-old girl who presented to the Thyroid Department for an asymptomatic palpable neck mass for 1 year. The high levels of calcium, ionized calcium, and parathyroid hormone level along with parathyroid scintigraphy studies suggested primary hyperparathyroidism. Parathyroid carcinoma was confirmed by biopsy...
Early resorption of an artificial bone graft made of calcium phosphate for cranioplasty: case report
The treatment of uncomplicated osteoma consists of an en bloc resection, or curettage, of the tumor, followed by cranioplasty. Here, we present a case report of a patient treated for a parietal osteoma, followed by a calcium phosphate cranioplasty, with early resorption after 3 months, which was presented by a sinking flap above the resection area. This case suggests that synthetic cranioplasty...
Thymic tumors are classified as stage III when they clearly invade the surrounding structures: pericardium, great vessels (superior vena cava, innominate veins, ascending aorta, and main pulmonary artery), lung parenchyma, phrenic nerves, and chest wall. Surgical treatment with or without induction therapy should always aim to complete resection removing en bloc all the involved structures. Als...
The authors report the case of a 28-year-old female patient with a giant cell tumor originating from the rib. The tumor, measuring 25 x 17 cm, occupied the entire hemithorax and caused atelectasis of the left lung. This tumor was a benign mesenchymal neoplasm, which rarely affects the ribs. A thoracotomy involving en bloc resection of the chest wall and tumor was performed. Despite the large di...
