We have recently experienced a case of mammary hamartoma in 29-year-old woman. Hamartoma of the breast is a rare benign tumor-like lesion which is characteristically well demarcated by thin layer of fibrofatty tissue and composed of essentially normal mammary tissue with mammary glandular structure and fibrous stroma containing variable amounts of fat. The lobular architecture is relatively well preserved. It can be readily recognized, but should not be confused with fibroadenoma or mammary dysplasia. It also shows characteristic mammographic picture.

PURPOSE: To investigate nutritional status of inpatients by using subjective. and objective evaluation methods and to find the relationship between them. METHOD: The subjects were 101 inpatients with medical health problems at a university hospital. Nutritional status was evaluated by the Subjective Global Assessment (SGA) and physical assessment including percentage of weight loss, serum albumin, hemogloin, and hematocrit. Data were analyzed using frequency, percentage, mean, Kendall's tau. RESULTS: Grouping by the SGA, 61.4% were classified as severe malnutrition group. When applying the objective methods{physical assessment). 1.9~42.6% were diagnosed as malnutrition each item. The percentage of weight loss during previous 1-6month(r=.43~.54. P=.0001), serum albumin(r=-.26, P=.0003), hemoglobin of male(r=-.38, P=.0001), and hematocrit of male(r=-.34, P=.0001) were significantly correlated with SGA score. The coincidence rate of nutrition evaluation between the objective methods and SGA were 27.7 35.6%, 20.8%, 47.5%, 58.4% in percentage of weight loss, albumin, hemoglobin, and hematocrit. CONCLUSION: These findings showed a majority of inpatients were exposed to the risk of malnutrition. We recommend to evaluate inpatients' nutritional status periodically and to develop nursing intervention to solve their nutritional problems.

The term malignant mesenchymoma has been applied to those tumors of the soft tissue of mesenchymal origin which are composed of tumor cells differentiating into two or more unrelated malignant forms in addition to the fibrosarcomatous element. Recently authors experienced a case of malignant mesenchymoma in the right axillary area. Microscopically the sarcoma revealed multiple pattern of differentiation, including liposarcoma, malignant schwannoma, fibrosarcoma, malignant fibrous histiocytoma and rhabdomyoblastoma. The presence of rhabdomyblastic cells were proved by immunochemical study utilizing desmin. This patient was treated with surgical excision and radiation.

Adenoid cystic carcinoma of the esophagus was regarded as an esophageal counterpart of the more common adenoid cystic carcinoma of the salivary gland. However it is a rare lesion which has more malignant differentiations and thus shows more aggressive clinical behaviors than the latter. Although many authors think that this tumor arises from the submucosal esophageal gland, its histogenesis is still in dispute. A 60-year-old male patient had a tumor in the middle third of the esophagus which was incidentally found during gastrofiberscopy. The tumor was 1.5 cm sized and covered with intact mucosa. The patient underwent Ivor Lewis operation, and the postoperative complication of ARDS eventually subsided. On microscopic examination of the surgically resected specimen, the adenoid cystic carcinoma which was mainly confined to the submucosa extended to the proper muscle layer, however no regional lymph node metastasis was present. The patient is still alive and well 6 months after the surgery.

OBJECTIVES: The purpose of this study is to identify the role of individual innovation to demographic variables for determining IT adoption behaviors. This study also examines the effect of individual innovation on IT adoption behaviors across IT types. METHODS: To verify the invariant effect of individual innovativeness, two groups of persons working in the health care field were surveyed. The first study subject group was radiologists and their adoption of e-purchasing the second group was emergency rescue crews and their adoption of GPS. RESULTS: Adopter categories in innovations (ACI) as the measurement of individual innovation were a significant variable in both studies. Innovative adopters were more likely to use new IT tools than the majority of early adopters, and the early majority was more likely to adopt IT than the laggards. After merging the two data sets into one for testing the role of IT types as a moderator, the significance of ACI did not change, compared to the two separate analyses. In the merged data set, innovative adopters were 2.34 times more likely to be adopters than the early majority. The early majority was 2.32 times more likely to be adopters than laggards. Moreover, there were no moderating effects of IT types. Thus, there were no reversed adoption rates according to levels of ACI and demographic variables. CONCLUSIONS: ACI has invariant effects on IT adoption behaviors regardless of IT types and demographic differences. To implement a new innovation, understanding individual innovativeness will provide more sophisticated implementation strategies for health care organizations and appropriate education programs for their employees.

Carcinosarcomas of the female genital tract have generally been regarded as a type of sarcoma. Recent studies, however, suggest the tumor may be more closely related to carcinoma and may represent metaplastic carcinoma in histogenesis. We analyzed clinicopathologic and immunohistochemical features of 10 carcinosarcomas to evaluate the relative importance of the carcinomatous and sarcomatous components in metastasis and recurrence. The primary tumor originated in the uterine body in seven cases, the uterine cervix in two and the ovary in one. Patient,s ages ranged from 54 to 71 years (mean, 64). The most common symptom of the uterine mass was vaginal bleeding. The median survival time was 21 months following diagnosis in five cases. Surgico-pathologic FIGO stages of five patients who received an operation were stage III and IV, but clinical FIGO stage of three patients (60%) among them were I. Lymphovascular invasions were identified in seven areas; five vascular invasion lesions showed the carcinomatous component alone, one the sarcomatous component alone, and remained one admixture of both components. Metastatic and recurrent lesions to the paraaortic lymph node, ovary, pelvic wall, or vaginal vault showed characteristically carcinomatous component only. Immunohistochemically, positive reactions for cytokeratin and epithelial membrane antigen were noted in the sarcomatous component of five cases. Vimentin positivity was detected in carcinomatous component of three cases. We conclude that the dominant element in carcinosarcomas of the female genital tract is the carcinomatous component. The survival rate of carcinosarcoma is extremely poor. The surgico-pathologic stage is better indicator of survival than the clinical stage. Immunohistochemical findings suggest that carcinosarcoma may represent a metaplastic carcinoma in histogenesis.

Endometriosis in the abdominal wall following Cesarean section is one of the very rare condition among the extrapelvic endometriosis. Although benign, endometriosis possesses the unique ability to invade tissue and to disseminate or metastasize by hematogeneous, lymphatic route, or direct implantation. We reported the case with brief review of the literature.
