Cleidocranial Dysplasia

Ancient (degenerated) schwannomas are benign tumors that display pronounced degenerative changes including cyst formation, calcification, hemorrhage, and hyaliniz ation. The tumors are usually infiltrated by large numbers of inflammatory cells such as neutrophils, lymphocytes, siderophages, and histiocytes. They are located in deep locations such as the retroperitoneum and must be differentiated from malignant soft tissue tumors because spindle cells with nuclear atypia may be present in the fine needle aspiration biopsy. The cytologic findings of two cases of ancient schwannoma occurring in posterior mediastinum and retroperitoneum, respectively, are described. Computerized tomographic findings of both cases showed changes of cystic degeneration or necrosis. A case occurred in retroperitoneum revealed features of destruction of vertebral body to suggest a malignant soft tussue tumor radiologically. The cytologic findings of aspiration biopsy of both tumors revealed that the tumor cells were spindle in shape with elongated nuclei. Some of tumor cells were arranged in a palisading fashion. Cell structures that resemble the Verocay bodies were observed. Some of the tumor cells showed pleomorphic bizarre nuclei, but no mitotic activity or chromatin clumping was seen. Inflammatory cells, siderophages and histiocytes were scattered in fibrillar material. These cytologic findings are important in the diagnosis of ancient schwannoma and in the differentiation of this tumor from the malignant spindle cell tumor.

Microcystic meningioma, a distinct morphological variant of meningiomas, is histologically characterized by a vacuolated appearance with multiple cystic spaces lined by vacuolated or stellate-shaped tumor cells. We report a case of microcystic meningioma occuring in right frontoparietal area of 42-year-old woman, with emphasis on differential diagnosis, along with a review of literatures. Immunohistochemically, most of the tumor cells demonstrated positive immunoreactivity for both epithelial membrane antigen and vimentin. Electron microscopy showed that the extracellular space was extensive, where eletron-lucent material was occasionally seen. The tumor cells had long cytoplasmic processes showing complex interdigitation and a large number of desmosomes.

Stabilization of the unstable spine created by the posterior decompression is as important as the decompression itself in the treatment of spinal stenosis. The purpose of this study is to evaluate the effectiveness of C-D pedicle screw fixation in stabilization after lumbar decompression, in reduction of spondylolisthesis and in restoration of the lumbar sagittal curvature. C-D pedicle screw fixation was performed in 102 spinal stenosis patients after posterior lumbar decompression and fusion during the period from March 1987 to December 1988. Their age ranged from 15 to 72 years with an average of 49.1 years. There were 34 males and 68 females. The follow up was from 6 to 21 months with an average of 12.5 months. The causes of spinal stenosis were degenerative in 50 patients, spondylolisthesis in 39, iatrogenic in 9 and degenerative lumbar scoliosis in 4. Objective clinical results showed significant improvement of claudication, SLR limitation, motor weakness, sensory and DTR changes in most patients. Following results were obtained from the study of C-D pedicle screw fixation after posterior decompression in lumbar spinal stenosis.1. C-D pedicle screws provide the secure fixation that allows early ambulation and shorter hospital stay. 2. C-D pedicle screws enable the reduction of spodylolisthesis at the time of posterior stabilization. 3. C-D pedicle screw fixation is successful in the restoration and maintenance of sagittal curvature of the lumbar spine. 4. C-D pedicle screw fixation enables the correction of scoliosis at the time of posterior decompression.

Antiphospholipid syndrome is a thrombotic disorder and the serologic marker of the syndrome is antiphospholipid antibody(lupus anticoagulant, anticardiolpin antibody, or both). In a 13-year-old girl who presented with dyspnea, pulmonary embolism and femoral vein thrombosis were demonstrated by lung scan and abdominal ultrasonography. She had 3 out of 11 criteria for the diagnosis of SLE, such as thrombocytopenia, positive antinuclear antibody, low C3 and high anti-ds-DNA Ab, but did not meet whole criteria. And lupus anticoagulant was positive. She was treated with anticoagulants(heparin and wafarin) and prednisolone. Antiphospholipid antibody(lupus anticoagulant and anticardiolipin antibody) should be checked in children with thrombosis occurring without a known predisposing cause.
