BACKGROUND: Mycobacterial culture is a confirmatory test to detect M.tuberculosis, but it takes at least 6 weeks to diagnose. PCR is a rapid and sensitive method, but it is known that PCR has a high false positive rate due to contamination, and a high false negative rate due to inhibitors. It is also known that LCR and PCR-Hybridization, recently developed methods, are more specific methods than PCR in terms of detection M.tuberculosis. In this study, we estimated the clinical utility of in house PCR, LCR and PCR-Hybridization for the detection of M.tuberculosis. METHODS: We evaluated 75 specimens, upon which M.tuberculosis culture based testing was requested, by PCR LCR, and PCR-Hybridization and compared results. Mycobacterial culture was performed on 3% Ogawa media for 8 weeks, and an in house PCR, LCx Mycobacterium tuberculosis assay kit(Abbott Laboratories, North Chicago, III) and the AMPLICOR M.tuberculosis test kit(Roche Molecular Systems, Inc. Branchburg, NJ, USA). RESULTS: In the view of the culture results, the sensitivities of the three tests were 40%, 80%, and 100% and their specificities were 98.6%, 94.3%, and 94.3%. CONCLUSION: LCR and PCR-Hybridization and rapid and sensitive methods for detecting M.tuberculosis in clinical laboratories.

The term "pineal anlage tumor" has been recently proposed and few cases have been reported. We report the first Korean case of pineal anlage tumor in a 6-year-old girl who complained of headache and vomiting for 2 months. Brain MRI revealed a well defined, lobulated, calcifying mass in the pineal region. Tumor was totally removed. Pathological examination revealed a primitive pineal parenchymal tumor with melanotic epithelial component that was similar to histologic findings of melanotic neuroectodermal tumor of infancy, so-called retinal anlage tumor and of the developing pineal gland. The tumor was composed mostly of small, undifferentiated cells, Flexner-Wintersteiner rosettes, and ganglionic differentiation. The tumor also contained the cartilage and skeletal muscle cells.

Liposarcoma of the male breast is rare. In English literature, nearly 90 tumors of this type can be found, but the majority of citation is female without detail descriptions of gross or microscopic features. Recently, we experienced a case with pleomorphic liposarcoma of the breast. This 62-year-old male patient presented with tumorous mass of right breast for 3 months ago. He underwent radical mastectomy under the impression of breast cancer. Received specimen was a breast and attached nodular bulging mass. The serial section reveal a relatively defined nodular mass consists of yellowish and glistened bulging tumorous lesion, measuring 5x4.5x5cm. Microscopically, there were multiple pleomorphic giant cells composed of plump esoinophilic or microvesiculated cytoplasm and bizarre nuclei with prominent nucleoli. These cells were positive staining for oil-red O. Ultrastructurally, variable sized numerous fatty vacuoles in the cytoplasm were seen.

This study was performed to fine out the possible causes of primary infertility in female and to provide some diagnostic and therapeutic modalities. A total of 104 cases of endometrium in primary infertility was obtained from the pathology files of Chosun University Hospital and Kwang-ju Christian Hospital during the period of 5 years and 10 months from January, 1984 to October, 1989. The endometrial biopsies were taken on the first of menstruation and classified according to Noyes, Hertig and Rock's criteria. Histologic findings which were compatible with their normal menstrual cycle (premenstrual of late secretory phase and bleeding phase) were noted in 52 cases (50%). Abnormal 52 cases (50%) revealed deficient secretory phase in 36 case (34.6%), proliferative phase in 5 cases (4.8%), irregular proliferation and chronic nonspecific endometritis in 4 cases (3.8%), respectively, endometrial hyperplasia in 3 cases (2.9%), tuberculous endometritis in 2 cases (1.9%), and asynchronous cycle in 1 case (1%). Among the case of dissociated delay was 21 cases (20.2%) and coordinated delay was 15 cases (14.4%). Therefore, deficient secretory phase with dissociate delay was most common abnormal endometrial finding in cases of female primary infertility. The peak age distribution of the female primary infertility in this study revealed 73 cases (63.8%) in patients between the age of 25 and 29. This finding indicated that there was no significant relationship between the age distributions and the endometrial histopathologic findings.

A total of 51 cases of pleomorphic adenoma was obtained from the pathologic files of Chosun University hospital from january, 1980 December, 1989. The studies of clinical, microscopic, immunohistochemical, and electronmicroscopic examination showed the following results. The peak age incidence of the pleomorphic adenoma in this study was in the 5th decade and no significant difference in the incidence between male and female patients was observed. The most common histologic type of myoepithelial data showed positive reactions of the myoepithelial cells to cytokeratin and S-100 protein in the solid, myxoid, and chondroid area. The electronmicroscopic examination of the myoepithelial cells revealed myofilaments, dense bodies, desmosomes, and basement membrane suggesting epithelial origin of these cells. In conclusion, the pleomorphic adenoma seems to be derived from epithelial component and the variable stromal change may be derived from modified myoepithelial cells considering the results of immunohistochemical and electron microscopic study.
