Lipid cell tumors of the ovary are among the rarest of the functional ovarian neoplasms. Recently, authors experienced a case of lipid cell tumor of the left ovary in a 19 year old female, who presented with amenorrhea and hirsutism for 4 years. Grossly, the ovary was well encapsulated, and measured 6.5x6x4.5 cm. Cut surface show homogenous yellowish bulging neoplastic tissue and peritheral displaced normal ovarian tissue. Microscopically, neoplastic cells were composed of rounded and polyhedral cells, arranged in nests seperated by rich vascular networks. On the basis of the author's findings and the evidence available in the literature, we determined this case as ovarian lipid cell tumor.

A 55 year old male complain right shoulder pain and right upper quadrant pain about three months. He was a heavy alcoholism. Highly selective angiography, CT scan and operation findings suggest primary malignant neoplasm of the liver. Right hepatic lobectomy and partial diaphragmectomy was done under impression of heaptocellular carcinoma. The specimen measured 15x11x9 cm and disclose relatively hard and nodular mass devoid of cirrhotic changes. Cut surface show unilobar large mass measuring 11x8x6 cm and bearing brightly yellow discoloration and multifocal hemorrhagic necrosis. Histological characteristics were diffuse proliferation of large neoplastic cells with ample cytoplasm, containing granular materials, erythrophagocytosis, neutrophagocytosis and hemosiderin pigments. Atypical and bizarre mitosis and multinucleated giant cells bearing abundant erythro and neutrophagocytosis were frequently seen. The large or vesicular nuclei were irregular, with occasional deep indentations and revealed sharply defined nuclear membrane, coarse chromatin and conspicious nucleoli. Ultrastructurally the cytoplasm of neoplasltic cells had lysosomal granule, phagolysosome, phagocytized material and residual bodies. Immunohistochemical stains for alpha 1-antitrypsin, alpha 1-antichymotrypsin, vimentin and lysozyme showed positive reactions, but, alpha fetoprotein, cytokeratin, S-100 protein, factor VIII, complement 3 receptor and carcinoembryonic antigen were negative. Alpha-naphtyl acetate esterase activity in paraffin embedded tissue ribbon showed negative reaction. These findings show compatible with primary malignant lymphoma, true histiocytic type, (histiocytic sarcoma, Kupffer cell carcinoma) of the liver.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast occurs in premenopausal women and is characterized by anastomosing channels lined by spindle cells. It has been suggested to be of hormonal origin. This unusual condition may also be mistaken for a vascular tumor. We analyzed eight cases of PASH of the breast in Samsung Cheil Hospital from 1992 through 1998. All patients were premenopausal and had painless breast lump. Clinical diagnoses were fibroadenomas. Grossly, the masses were well circumscribed, nonhemorrhagic and measure 2.2 to 5 cm. Histologically, they consisted of complex interanastomosing channels lined by slender spindle cells, which resembled low grade angiosarcoma. Cells that line the interanastomosing channels showed no immunoreactivity for Factor VIII and electron microscopic findings consistent with fibroblast. All patients were treated with surgical excision and none of them had recurrence for 1 to 69 months (mean: 19 months) postoperatively. Pathologic diagnosis of PASH may be difficult unless the pathologists are aware of the presence of a mass lesion and appreciate the characteristic stromal changes. PASH should be included in the differential diagnosis of a circumscribed mass, especially in the premenopausal women.

Recently developed new classifications (Holland, Van Nuys, modified Lagios) of ductal carcinoma in situ (DCIS) linked to outcome have emphasized the importance of nuclear morphology rather than architecture. We have evaluated these three classifications in ductal carcinomas composed of in situ and invasive carcinomas. The reproducibility of three classifications was assessed (n=49), and the histological grade of the DCIS was compared with the histologic differentiation (modified Bloom & Richardson method) and nuclear grade (modified Black method) of the coexisting invasive ductal carcinoma (n=45). According to Holland classification, the DCIS component was poorly differentiated in 51.0%, intermediately differentiated in 40.8%, and well differentiated in 8.2%. Using the Van Nuys classification, the DCIS component was group 3 (high grade with or without necrosis) in 44.9%, group 2 (non-high grade with necrosis) in 28.6%, and group 1 (non-high grade without necrosis) in 26.5%. According to the modified Lagios classification, the DCIS component was high-grade in 42.8%, intermediate-grade in 32.7%, and low-grade in 24.5%. The histologic grades of the three classifications revealed significant correlations between Holland and Van Nuys classification (p<0.0001) and between Holland and modified Lagios classification (p<0.0001), especially in poorly differentiated/group 3/high-grade DCIS. The reproducibility of classification of the DCIS was 71.4% in the Holland, 61.2% in the Van Nuys, and 55.1% in the modified Lagios classifications. The grade of the DCIS showed significant correlation with the grade of coexisting invasive ductal carcinoma (p<0.0001), especially in poorly differentiated/group 3/high-grade DCIS. In conclusion, DCIS grade, determined by the Holland, Van Nuys or modified Lagios classifications, is closely correlated with the histologic grade of the invasive ductal component in tumors composed of in situ and invasive ductal carcinoma, and may be a useful factor to estimate clinical behavior of DCIS. In our experience the Holland classification is recommended for DCIS classification due to its high reproducibility.

PURPOSE: The purpose of this study was to describe perceived conception of health, family support and health promoting behavior; as well as to assess factors that influence health promoting behavior. METHOD: Study participants were 165 elderly people over the age of 65, living in C city. The instruments were Laffery's health concept scale, the family support scale by Kang, and the health promoting behavior scale by Walker et al. RESULTS: 1. The scores for level of health concept ranged from 28 to 112, and had a mean score of 75.16. The scores for level of family support ranged from 11 to 55, and had a mean score of 41.55. The scores for health promoting behavior ranged from 40 to 160 with mean score of 98.07. For health promoting behavior the participants revealed that the most frequent practices were in nutrition, and the least frequent, in exercise. 2. Higher levels of health conception and family support were correlated with an improving level of health promoting behavior . 3. The factor most influencing health promoting behavior in elderly people was family support. Family support accounted for 11% of the variance in health promoting behavior. A combination of health conception, education level and dwelling pattern accounted for 23% of the variance in health promoting behavior. CONCLUSION: Perceived health conception and family support were identified as important variables for health promoting behavior in elderly people.

PURPOSE: This study was carried out to identify the factor of decisional balance for exercise. This was composed of a set of variables at the level of decision making when the elderly decide to do exercise. It was used to classify and identify the characteristics of the stages of change for exercise to which the elderly belong, and was used to identify the variables of decisional balance which influence the stage of change for exercise in the elderly. METHODS: Convenient samples of 198 subjects over age 60 in Seoul( mean age=70) were selected from community living, mentally competant older adults and the data was collected from April 1, 1999 to May 31, 1999. The research instrument was the Decisional Balance Measure for Exercise(Marcus &Owen., 1992), Stage of Change Measure(Marcus et al,1992). The data was analyzed by SAS Program. RESULTS: 1. According to stage of change measure, without missing data,191 subjects were distributed in each stage of change for exercise: 50 subjects(26.1%), 7 subjects (3.6%), 52 subjects(27.2%), 4 subjects(2%), and 78(40.8%) belonged to the pre- contemplation stage, contemplation stage, preparation stage, action stage and maintenace stage. 2. Factor analysis identified 3 factors of decisional balance as appropriate factors for exercise of the elderly and named by researchers; 1)'Perceived Physical-psychological benefit', 2)'Perceived Physical-psychological burden', and 3)'Perceived time burden'. 3. The analysis of variance showed that the two components Perceived Physical - psychological benefit(F=45.95, P=.0001), and Perceived Physical-psychological burden (F=26.52, P=.0001) were significantly associated with stage of change. 4. Through the discriminant analysis, it was found that both 'Self Perceived Physical - Psychological benefit' and 'Perceived Physical-Psychological burden' were the influential variables in discriminating the three stages of change(pre-contemplation, preparation, and maintenance). CONCLUSION: Results are consistent with the application of the Transtheoretical model, which has been used to understand how people change health behaviors. Even though this study is a cross-sectional, not a longitudinal study, the findings of this study give useful information for exercise intervention about especially the factors relating to decision making for exercise of the elderly in the different stages of change of exercise.

The purpose of this study was to identify causal relationships among variables of transtheoretical model for exercise in the elderly. A predictivel model explaining the stage of change was constructed based on a transtheoretical model. Empirical data for testing the hypothetical model was collected from 198 old adults over 60 years old in a community setting in Seoul, Korea in April and May,1999. Data were analyzed by descriptive statistics and correlational analysis using pc-SAS program. The Linear Structural Modeling (LISREL) 8.0 program was used to find the best fit model which predicts causal relationship of variables. The fit of the hypothetical model to the data was X2=132.85. (df=22, p=.000). GFI=.88, NNFI=.35, NFI=.77, AGFI=.59 which was not favorable but the fit of modified model to the data was X2=46.90. (df=27, p=.01).GFI= .95, NNFI=.91, NFI=.92, AGFI=.87) which was more than moderate. The predictable variables of stage of change for exercise of the Korean elderly were helping relationship, self cognitive determination, conversion of negative condition in process of change and efficacy for exercise . These variables explained 68% of stage of change for exercise of the Korean elderly.

Purpose: This study was performed to identify the factors that change exercise behave. This study will also classify and identify the characteristics of excercise stages to which the elderly belong Also, to identify the processes of change which influence on the changes in exercise performed by the elderly. Methods: Convenient samples of 198 subjects over the age 60 in Seoul Korea(mean age=70) were selected from elderly communities and were all mentally conpetant older adults. The data were collected from April 1,1999 to May 30, 1999. The research instruments were measured the change in exercise (Marcus et al., 1992b), such as Stage of Change measure(Marcus et al,1992a). The data were analyzed by SAS Program. Results: 1. According to the measure of change without missing data, 191 subjects were distributed each stage of change for exercise: 50 subjects (26.1%), 7 subjects (3.6%), 52 subjects (27.2%), 4 subjects (2%), and 78 (40.8%) belonged to the precontemplation stage, the contemplation stage, the preparation stage, the action stage and the maintenace stage. 2. According to the factor analysis, 6 factors of change were identified as appropriate processes of change and were named by the researchers. The names were; 'Supportive helping relationship', 'Self cognitive determination', 'Environmental reinforcement', Consciousness raising', Reinforcement of negative condition and 'Conversion of negative condition'. 3. According to the stage of change, there were significant mean differences in the 'Supportive helping relationship(F=22.04, p=.0001)', 'Self cognitive determination (F=50.87, p=.0001)', 'Reinforcement of negative condition(F=7.84,p=.0006)'. 4. Through the discriminant analysis, it was found that Self cognitive determination is the most influential variable as one of the processes of change which can discrimiate the three stages of change (precontemplation, preparation, and maintenance). Also the next significant variable was Reinforcement of negative condition. Conclusion: The process of the dey change is one of concepts of The transtheoretical model known as strategies and the techniques people use as they go through the different stages of change. Even though this study is cross- sectional not longitudinal study, the finding of this study gives useful information for exercise intervention, by using this strategy of exercise for elderly in different stages of change in exercise.
