- 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.

- 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.

- 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.
