Sarcoma is a malignant tumor originated from bone, cartilage, fat tissue, nerve, blood vessel, bone marrow, endothelium, etc. and for this reason it exhibits considerable variation not only clinical but histologic appearance. Osteosarcoma occurs chiefly in young persons and in patients older than 40 years it is usually associated with Paget's disease, irradiated bone, multiple hereditary exostosis or polyostotoc fibrous dysplasia and sometimes with preceding trauma. Radiographically it is divided into three forms: an osteoblastic or sclerosing type, an osteolytic type, and mixed type. Histologically it is divided into osteoblastic type, chondroblastic type, fibroblastic type. The treatment of osteosarcoma is radical excision, combined chemotherapy but the prognosis is poor and overall 5-year survival rate is 20-40%. We present two different type sarcomas of 22-year-old male and 56-year-old male patients which we performed surgical excision, combined chemotherapy and radiation therapy.

Fluorescence in situ hybridization (FISH) techniques allow the enumeration of chromosome abnormalities and from a great potential for many clinical applications. In order to produce quantitative and reproducible results, expensive tools such as a cooled CCD camera and a computer software are required. We have developed a Chromosome Image Processing System (Chips) using FISH that allows the detection and mapping of the genetic aberrations. The aim of our study, therefore, is to evaluate the capabilities of our original system using a black-and-white video camera. As a model system, three repetitive DNA probes (D18Zl, DXZI, and DYZ3) were hybridized to variety different clinical samples such as human metaphase spreads and interphase nuclei obtained from uncultured peripheral blood lymphocytes, uncultured amniocytes, and germ cells. The visualization of the FISH signals was performed using our system for image acquisition and pseudocoloring. FISH images were obtained by combining images from each of probes and DAPI counterstain captured separately. Using our original system, the aberrations of single or multiple chromosomes in a single hybridization experiment using chromosomes and interphase nuclei from a variety of cell types, including lymphocytes, amniocytes, sperm, and biopsied blastomeres, were enabled to evaluate. There were no differences in the image quality in accordance with FISH method, fluorochrome types, or different clinical samples. Always bright signals were detected using our system. Our system also yielded constant results. Our Chips would permit a level of performance of FISH analysis on metaphase chromosomes and interphase nuclei with unparalleled capabilities. Thus, it would be useful for clinical purposes.

OBJECTIVE: The purpose of this study was to determine whether intracytoplasmic sperm injection(ICSI) could overcome the defects of oocytes in IVF-ET patients with previous fertilization failure by conventional fertilization technique. Design: Retrospective study Materials and METHODS: A total of 119 ICSI cycles in 57 IVF-ET patients performed from May, 1995 to December, 1997 was enrolled. Subjects were divided into two groups: FR group included 66 ICSI cycles in 35 patients with normal sperm who underwent ICSI due to past history of failed or poor fertilization in the previous IVF-ET cycles, and OAT group included 53 ICSI cycles in 22 patients with severe oligoasthenoterato- zoospermia(OAT) which was defined as sperm concentration < 20 million/ml, mo#dlity < 30% and normal morphology < 4% by strict morphologic criteria. The outcomes of ICSI were analyzed and compared in both groups. RESULTS: The age of female patients, basal serum FSH level, and the numbers of oocytes retrieved and metaphase II oocytes were all comparable in both groups. The fertilization rate after ICSI was similar in both groups(68.7+/-25.3% vs. 67.7+/-24.5%), as were the cleavage rate of normally fertilized oocytes(93.1+/-21.4% vs. 89.3+/-21.6%), the number of embryos transferred(4,00+/-1.98 vs. 4.64+/-2.10), and cumulative embryo score(CES) indicating the quality of embryos(47.3+/-33.2 vs. 54.1+/-33.2). The implantation rate(4.3+/-10.5% vs. 3.8+/-11.0%) and the clinical pregnancy rate per cycle(15.2% vs. 13.2%) were also comparable in both groups. CONCLUSIONS: Although it has been shown that there is a higher risk of chromosomal abnormalities in oocytes from IVF-ET patients with pevious failed or poor fertilization, higher implantation and clinical pregnancy rates wer#e not observed in patients with OAT following ICSL Therefore, the functional defect of sperm such as loss of capacitation, defect of aaasome reaction, and abnormality of nucleus decondensation should be also considered in patients with previous failed or poor fertilization.

Phyllodes tumor of the breast is a relatively rare fibroepithelial tumor. Turner syndrome is a condition that affects approximately 50 per 100,000 females and includes total or partial absence of one X chromosome in all or part of the cells, reduced final height, absence of female sex hormone, and infertility. In this case report, we describe the first case of a benign phyllodes tumor mimicking a malignancy at breast US in a 26-year-old woman with Turner syndrome who had been undergoing hormone replacement therapy.

The proportion of male factor infertility due to quantitative and qualitative sperm disorders is approximately 50-60% in infertile couples. In IVF-ET, lower or failed fertilization of oocytes usually results from subnormal count of total motile sperms, but this may occur in infertile couples even with normal sperm count. It has been suggested that some functional defects in sperms are responsible for lower or failed fertilization. Routine semen analysis based on numerical background has limits for the assessment of fertilization capacity of sperm in infertile males, and the andrologic test for the prediction of fertilization capacity must be objective, repeatable, quick, economic, and easily applicable for the clinical settings. The purposes of this study were to develop the analysis method of strict morphology of sperm using the strict criteria as a simple, inexpensive and useful test of sperm fertilization capacity, to establish the normal fertile range and the cut-off value of strict morphology, and to evaluate the validity of strict morphology as a prognostic indicator of fertilization capacity in IVF-ET. In establishing the effectiveness of strict morphology of sperm, ROC curve was used. Among the various thresholds for the prediction of fertilizing ability, normal morphologic value 10.0 corresponding to the value with higher sensitivity and lesser false positive rates was determined as a cut-off value. Using this cut-off point, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of strict morphology for the prediction of fertilization capacity was 73.9%, 81.0%, 80.6%, and 72.7%, respectively. To evaluate the clinical validity of strict morphology as a prognostic indicator of fertilization capacity, this cut-off point was applied to 133 patients undergoing IVF-ET. For the prediction of fertilization rate >30% in IVF-ET, the sensitivity, specificity, PPV, and NPV was 77.3%, 77.8%, 87.2%, and 63.6%, respectively. In conclusion, the strict morphology of sperm is one of the most simple and useful test for the assessment of fertilization capacity of sperm and the prediction of IVF-ET outcomes in infertile couples.
