Struma ovarii, the most common monodennal teratoma of the ovary, causes diverse problems in differential diagnosis. The literature on the pathology of struma ovarii has focused principally on the problem of formulating criteria of malignancy. In contrast, unusual gross and microscopic features of struma ovarii and its resultant problems in differential diagnosis have received relatively little attention. We report an ovarian teratoma which was almost entirely cystic, causing the diagnosis of struma to be overlooked. The removed ovarian tumor showed all the features of adenomatous goiter of the thyroid gland. The lining epithelium of the cysts was frequently flattened, and the follicles in the cyst wall were few and atrophic. The patient was a 58-year-old woman who was found to have an ovarian tumor by routine monographic examination

Multilocular cystic renal cell carcinoma is a distinct subtype of renal cell carcinoma with its pathological characteristics and good prognosis. Multilocular renal cysts and renal cell carcinoma with cystic change are important differential diagnoses. We report a case of multilocular cystic renal cell carcinoma in a 37-year-old woman who came to the hospital because of the right renal mass. The removed right kidney showed a 6x4 cm well defined cystic mass in the lower pole. On cut section there were multiple cavities in the mass, filled with serosanguineous fluid and focal yellowish solid area. Microscopically, these cysts were lined by a single layer of flat or cuboidal cells consisted of clear cytoplasm with small central nuclei. In some portions of the tumor, the clear neoplastic cells formed sheets within the septa or walls of the cysts.

Sarcomatoid renal cell carcinoma is an uncommon tumor that has to be distinguished from renal carcinosarcoma. We have described three cases of sarcomatoid renal cell carcinoma showing different clinical and light microscopic features. An ultrastructural study of the tumor cells from the sarcomatoid area revealed frequent desmosomal junction, confirming the epithelial nature of the neoplasm. All three cases showed an aggressive clinical course and tended to invade adjacent organs or tissues. We believe that an histological and immunohistochemical examination in conjunction with an electron microscopic examination are necessary to diagnose sarcomatoid renal cell carcinoma.

Neoplasms showing both carcinomatous and sarcomatous features are well established, and have been reported in practically every organ where carcinoma can occur. But the difference in terminology and difficulties in histopathologic interpretation have hampered adequate understanding of these neoplasms. We report a case of carcinosarcoma in the recurrent form of serous cystadenocarcinoma of the ovary. The patient was a 64-year-old female who underwent total hysterectomy and bilateral salpingoophorectomy three years ago, due to perforated papillary serous cysta denocarcinoma of the right ovary. Recurrent pelvic masses contained both carcinomatous and sarcomatous components. Morphological transition between carcinomatous and sarcomatous components, and epithelial characteristics in the sarcomatous component by immunohistochemistry were recognized. We postulate the histopathogenetic mechanism based on the phenotypic conversion of carcinoma into sarcoma in the carcinosarcoma.

A case of an ovarian mucinous cystadenocarcinoma with mural nodules of anaplastic carcinoma is reported. The patient was a 46-year-old female with a right ovarian cystic mass and underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. The patient died of the disease in five months. Macroscopically, the right ovarian cyst wall contained numerous well-demarcated mural nodules. Histologically, the cysts were mucinous cystadenocarcinoma, and the nodules were composed of sarcoma-like spindle and polygonal cells with atypia and numerous mitoses. Spindle cells in the mural nodule showed epithelial characteristics by electron microscopy and immunohistochemistry. This case supports an epithelial origin of the mural nodule of anaplastic carcinoma in ovarian mucinous tumors.

Total 40 cases of serial bone scans with Tc99-m-MDP performed on less than 24 hour, 2nd day, 3rd day, 5th day, 1 week, 4 week, 12 week and 1 year respectively after fractures in tibia were analysed. All 5 cases of bone scans performed within 24 hour after injury showed increase in generalized tracer uptake and 3 cases of them(60%) showed localized increase in tracer uptake at the fracture sites. The earliest bone sean performed 9 hour after injury showed generally and locally increased uptake at the fracture sites. All 5 cases of bone scan performed 1 year after injury sinowed localized increased uptake at the fracture sites and 2 cases of them (40%) showed generalized increase in tracer uptake. Bone scans performed 12 week after injury showed the most outstanding increase in generalized and localized tracer uptake. Bone scans performed 1 year after injury showed decreased amount of generalized increase in tracer uptake (but more increased uptake than normal) but the localized increase in traccer uptake at the fracture sites was observed persistently. More study should be needed to clarify the corelationship between the presence of cold spots during the fracture healing and the union of the fractures. It is difficult to differentiate the old fractures to fresh fractures with the bone scans performed within 1 year because of persistent increase in tracer uptake to 1 year after fracture.

Peripheral cementifying fibroma is histomorphologically similar to the central cementifying fibroma, but this lesion is unique to the gingival mucosa and is only rarely seen in edentulous area. In most instances, it arise from interdental papilla, with 80% occurring anterior to molar region. This lesion appears to involve the maxilla and mandible equally, demonstrates the highest occurrence rate during the second decade of life, and affects female more frequently than male, with 4.3:1 to 3:2. Peripheral cementifying fibroma presents as firm, pedunculated or sessile mass with an intact or ulcerated surface depending on the presence of trauma. Microscopically, it reveals a highly cellular mass of connective tissue containing numerous plump, proliferating fibrolasts and several forms of calcification. Effective treatment requires deep excision, which includes the ligament and periosteum, followed by a thorough root scaling of the adjacent teeth. A reveiw of the literature and a report of a case of peripheral cementifying fibroma are presented.

BACKGROUND: Discrepancies exist in the existing researches regarding the association between social capital and self-efficacy, and most of these researches have been done in developed countries. The aims of this study were to assess the independent association between individual social capital and self-efficacy and to assess the associations between individual social capital, self-efficacy and self-rated health. METHODS: Data were obtained from the Gyeongnam health survey (6,500 persons) conducted in 2008. A self-administered questionnaire was additionally administered to gather information on demographic variables, health behaviors, chronic diseases, self-efficacy, social capital, and self-rated health status. Total study population was 3,843 as those with chronic diseases were excluded. RESULTS: In males, trust was positively associated with confidence and preference to task difficulty, and participation was negatively associated with confidence and positively associated with regulation and preference to task difficulty. In females, trust was positively associated with confidence and preference to task difficulty and negatively associated with regulation. Participation was positively associated with preference to task difficulty. In males, the odds for self-rated health status was better for persons with confidence (95% confidence interval, CI 1.088-1.705), trust (95% CI 1.172-1.821) and participation (95% CI 1.268-2.117). In females, the odds for self-rated health status was better for those with confidence (95% CI 1.250-1.803), preference of task difficulty (95% CI 1.019-1.683) and participation (95% CI 1.024-1.555). CONCLUSIONS: High social capital measured at an individual level may promote self-efficacy and health status.
