Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.

A case of fibrocalcifying pseudotumor occuring at a very unusual site, the intraosseous region of axis, is presented. Previous reports of similar lesions in skull base, intracranial parenchyme, soft tissue around spine, mediastinum, and pleura have been described under the designation 'fibro-osseouslesions' and 'calcifying pseudoneoplasm' The etiology, pathogenesis and natural course of the lesion are still unknown. Bvt the lesion is probably benign nature and reactive lesion rather than neo-plastic. Authors performed resection of lamina, spinous process, and a portion of pedicles and occipitocervical fusion to prevent spinal cord compression due to cortical expansion or fracture. Microscopically, amorphous, basophilic, hyaline, and chondroid calcifying masses were rimmed by palisading histiocytes and foreign body-type giant cells. No evidence of malignancy was found.

STUDY DESIGN: We retrospectively reviewed nine patients of lumbar extraforaminal disc herniation which underwent conservative or surgical treatment. OBJECTIVES: We evaluated the clinical characteristics, accuracy of diagnostic methods, and result of conservative or surgical treatment for the lumbar extraforaminal disc herniation. SUMMARY OF BACKGROUND DATA: Lumbar extraforaminal disc herniation represents an important component of lumbar disc herniation because of the difficulty in diagnosis and the difference in clinical characteristics and surgical approaches in contrast to usual intracanalicular disc herniation. MATERIALS AND METHODS: Nine patients which we have experienced from March 1994 to February 1997 were evaluated by physical examination, magnetic resonance imaging, EMG, and disco-enhanced computed tomogram. There were 4 males and 5 females, and average age was 42.4 years. RESULTS: The level of herniation was 4 cases at L4-5 and 5 at L5-S1. Radiating pain was chief complaint but low back pain was absent or mild. Accuracy of disco-enhanced computed tomogram was superior to that of magnetic resonance imaging. The results of conservative treatment were good in 2 cases(40%), fair in 2 cases(40%), and poor in 1 case(20%). And those of surgical treatment including partial laminectomy, medial facetectomy, and discectomy or extraforaminal approach were excellent in 3 cases(75%), good in 1 case(25%) according to the grading of MacNab. CONCLUSIONS: Lumbar extraforaminal disc herniation represents compressive symptoms of upper lumbar root of the involved level characteristically. Location and degree of disc herniation is an important tractor for determining the surgical approach, and disco-enhanced computed tomogram is a definite diagnostic method.

Axial displacement of an implant-supported prosthesis is frequently reported in clinical and laboratory studies. However, limited information is available about the behavior of the axial displacement of implant-supported prostheses functioning in intraoral situations. The present case report evaluated the three-dimensional displacement of posterior single implant-supported prostheses in 2different patients. Internal connection type implants were placed, and screw and cement-retained prosthesis (SCRP) type prosthesis were delivered after an appropriate healing period. Intraoral digital scans were performed using an intraoral scanner (Cerec Omnicam, Dentsply Sirona, USA) on the day of crown delivery and one week, one month, and one year after delivery. The amount of 3-dimensional displacement of the prosthesis was evaluated by using a digital inspection software (Geomagic Control X, 3D systems, USA). The axial displacement of implant-supported prosthesis occurred in both patients. Furthermore, the amount of displacement increased over time.

Angiosarcomas are rare tumors, seen most commonly in the skin and soft tissue of head and neck region. But it has been described in numerous body sites including thyroid, breast, liver, spleen, bone, etc.. Their biological behaviors depend on the microscopic grade, site of origin, and multifocality. We report the unique cytological features of an angiosarcoma in pleural fluid. A 61-year-old woman presented with a 6 month history of dyspnea on exertion and chest pain. Chest computerized tomography(CT) revealed multiple subpleural small nodules in the right lung and widespread air space consolidation and pleural effusion in the left lung. CT of liver revealed multiple small low attenuated lesion. The smears obtained from pleural fluid showed hypocellularity with a hemorrhagic background. The tumor cells were highly pleomorphic oval or spindle in shape and presented singly, in loose groups, in knitted syncytial aggregates, and in acinar pattern. Their nuclei had vesicular chromatin with delineated, thick nuclear membranes and occasionally a large eosinophilic, prominent nucleolus. The cytoplasm was plump, thin or projected in spindly fashion. Almost all tumor cells showed variable sized intracytoplasmic vacuoles and their nuclei were sometimes crescentic by a huge vacuole. Occasional binucleated tumor cells and mitotic figures were present. Cellular debris and streaky materials were identified. Needle biopsy specimen from the pleura revealed anastomosing slit-like spaces lined by pleomorphic tumor cells. The tumor cells showed a strong reactivity for CD31 and vimentin and focal weak reactivity for factor VIII-related antigen.
