A case of telangiectatic osteosarcoma of the proximal tibia of left leg in 19-year-old man was reported. Radiologically the tumor was aneccentric blow-out osteolytic lesion simulating aneurysmal bone cyst. Pathologically the tumor presented multiple blood filled cystic spaces and anaplastic spindle cells of osteoclastic type and focal osteoid deposition. The patient died 8 months after he underwent high above knee amputation followed by adjuvant chemotherapy. Distinct clinicopathologic finding of telangiectatic osteosarcoma was described with special emphasis on differential diagnosis.

We analyzed the clinical and laboratory features of ten children with acute megakaryoblastic lukemia (M7)and compared the findings with those reported in the literature. The diagnosis was supprted by ultrastructural examination of platelet peroxidase or immunophenotyping for glycoprotein IIb/IIIa. Of the ten children, five were girls and five were boys. The median age at diagnosis was 13 months. Two patients had prominent myelofibrosis and one patient had Down syndrome. Nine patients were treatd with low-dose cytosine arabinoside (10mg/m2)administered intravenously, or subcutaneously, or intramuscularly, twice daily in 21 day courses. Seven patients achieved hematologic response and three patients are alive without evidence of disease. The 4 year event free survival rate was30.0%. It is our impression that the prevalence of acute megakaryoblastic leukemia has been under-estimated, and low-dose cytosine arabinoside treatment may be of value in its management. This approach may be particularily useful in hospitals with scarce well-equipped facilities, since this protocol does not induce profound marrow hypoplasia and intensive supportive measures are not required as they would be with the use of more aggressive drug combination.

A variety of disease states are marked by prolonged and profound eosinophilia associated with localized or widespread eosinophilic infiltrates. Cardiac involvement maybe a major cause of morbidity and mortality of this disease. We report a case of acute peri-myocarditis with eosinophilia, which was confirmed as eosinophilic myocardilic myocarditis by endomyocardial biopsy.

A totally implanted venous access system was inserted in 19 children with cancer. The devices were utilized for the administration of antineoplastic drugs, parenteral fluids, antibiotics, and blood products. Total duration of implantation was 4,046 days for 23 implanted system (range 7-445 days). Complications included cather infection (0.247/100 catheter days), occlusion (0.692/100 catheter days), and dislodgement of needle (0.643/100 catheter days). There were major complications that necessitated removal of catheters, including systemic infections (0.09/100 catheter days) and complete occlusions (0.09/100 catheter days). The system was thought to be safe and convenient in chemotherapy, and permitted full physical activity.

PURPOSE: To evaluate the loss of bone mineral contents(BMC) in lumbar spine within the radiation field for cervical cancer treatment, BMC in the irradiated patient group was compared with that of a normal control group. METHOD AND MATERIALS: Measurements of BMC in the trabecular bone in lumbar spines(L3-L5) were performed in the both patient and normal control groups. Investigators used dual-energy quantitative computerized tomography(DEQCT) using photon energy of 120 and 80kVp. The numbers of patient and control groups were 43 in each with age distribution of fifth to seventh decade of women. The numbers of control group were 22 in fifth, 10 in sixth, and 11 in seventh decade, those of patient group were 14 in fifth, 14 in sixth, and 15 in seventh decade of women. The radiation field was extended to L5 spine for pelvic irrdiation with 45-54Gy of external radiation dose and 30Gy of high dose rate brachytherapy in cervical cancer. RESULTS: The BMC is decreased as increasing age in both control and patient groups. BMC in lumbar spine of patient group was decreased by about 13% to 40% maximally. The BMC of L3 and L4 a region that is out of a radiation field for the patient group demonstrated 119.5+/-30.6, 117.0+/-31.7 for fifth, 83.3+/-37.8, 88.3+/-46.8 for sixth and 61.5+/-18.3, 56.2+/-26.6mg/cc for seventh. Contrasted by the normal control group has shown 148.0 +/-19.9, 153.2+/-23.2 for fifth, 96.1+/-30.2, 105.6+/-26.5 for sixth and 73.9+/-27.9, 77.2+/-27.2mg/cc for seventh decade, respectively. The BMC of patient group was decreased as near the radiation field, while the lower lumbar spine has shown more large amounts of BMC in the normal control group. In particular, the BMC of L5 within the radiation field was significantly decresed to 33%, 31%, 40% compared with the control group of the fifth, sixth and seventh decades, respectively. CONCLUSION: The pelvic irradiation in cervical cancer has much effected on the loss of bone mineral content of lumbar spine within the radiation field, as the lower lumbar spine has shown a smaller BMC in patient group with pelvic irradiation in contrast to that of the normal control groups.

Wolf-Hirschhorn syndrome is a multiple malformation syndrome associated with mental and developmental retardation, resulting from a deletion at the short arm of chromosome 4 (4p16.3). We report a 11-year-old girl with Wolf-Hirschhorn syndrome, who was presented with severe growth and mental retardation along with characteristic features-frontal bossing, hypertelorism, downslanting of the palpebral fissures and fishlike lips. The diagnosis was confirmed by fluorescent in-situ hybridization (FISH).
