Classical osteoblastoma, atypical osteoblastoma, and osteosarcoma: a comparative study based on clinical, histological, and biological parameters.
OBJECTIVE To investigate the biological behavior of classical and atypical osteoblastomas in comparison to osteosarcomas. METHODS Based on histological parameters, 30 osteoblastomas were subclassified as classical osteoblastomas (23/30) or atypical osteoblastoma (high cellularity, prominent blue osteoid, and epithelioid osteoblasts--7/30). Comparative immunohistochemical and clinical analysis...
متن کاملOsteoblastoma-like Osteosarcoma of the Cuboid: A Case Report
Osteosarcoma most commonly arises in the long bones of the skeleton, and rarely develops in the bones of the foot. We describe a patient who presented with left foot pain, whose radiographic evaluation revealed a lytic destructive mass in the cuboid bone. A biopsy showed an osteoblastoma-like variant of osteosarcoma and the patient was treated with preoperative chemotherapy and amputation. Oste...
متن کاملOsteoblastoma-like Osteosarcoma of the Proximal Tibia: A Case Report
variant of osteosarcoma that may resemble osteoblastoma clinically, radiographically, and histologically and has been estimated to represent approximately 1% of osteosarcomas (1). Recently, reported involvements contain distal tibia, distal femur, proximal fibula and cuboid (1-4). To our knowledge, there has been no documented radiologic report concerning proximal tibial involvement. Radiologis...
متن کاملEpithelioid osteoblastoma: A histopathological dilemma between juvenile ossifying fibroma and low-grade osteosarcoma
Swelling of jaws with mixed opacity and lucency can have a spectrum of differential diagnosis, which includes odontogenic tumors, fibro‐osseous lesions and rarely the connective tissue neoplasms. With respect to the fibro‐osseous lesions, most of the time, histopathological features will be overlapping. In such cases, it is very important to arrive at a precise diagnosis for better treatment pl...
متن کاملUtility of immunohistochemical analysis for cyclo-oxygenase 2 in the differential diagnosis of osteoblastoma and osteosarcoma.
AIMS To study the immunoexpression of cyclo-oxygenase (COX) 2 in osteoblastomas (OBs) and osteosarcomas (OSs), and to assess the utility of immunohistochemical analysis for COX 2 in the differential diagnosis of the two tumour forms. METHODS The immunohistochemical features of COX 2 were studied in 11 OBs and 30 OSs, including 26 high-grade OSs (16 osteoblastic, 7 chondroblastic, and 3 fibrob...
