Cystadenoma*

The ultrasonographic findings of 49 ovarian cystadenomas were analized. The results were as follows: 1. Themost common age group was 3rd decade and most patients(83%) belong to active reproductive period. 2. In 80% ofserous cystadenoma the size of the tumor was ranged in 6–10cm in diameter. The large tumors of 16–20 cm indiameter were mostly mucinous cystadenomas. 3. Purely cystic appearance was the most common finding(40%) of serouscystadenoma and thick linear septation with and without solid component was the most common finding (38%) ofmucious cystadenoma. 4. Thick linear septation with solid component was not found inserous cystadenoma. 5. Welldefined nodular projection was found in 3 cases of serous cystadenoma but not identified in mucinous cystadenoma.

OBJECTIVE: The purpose of this study was (1) to evaluate the expressions of clusterin, bax, Ki-67, p53, and apoptotic index in epithelial ovarian tumors, borderline and malignant ovarian tumors, (2) to find out the correlation between their expressions and clinicopathological parameters, and (3) to evaluate the effect on the patient's survival according to their expressions. METHODS: The histological and clinical findings of 22 cases of ovarian cystadenomas, 44 cases of borderline tumors and 96 cases of carcinomas were evaluated. Expressions of clusterin, bax, Ki-67, p53, and apoptotic index were studied on paraffin-embedded tissue sections by immunohistochemical methods. RESULTS: The expressions of clusterin, p53, and Ki-67 were higher in ovarian carcinomas than borderline tumors. The overexpression of p53, and Ki-67 were frequent in high stage, poorly differentiated and bilateral ovarian carcinomas. The overexpressions of clusterin, bax, p53, and Ki-67 showed a statistically significant correlation with histologic type. Apoptotic index was higher in bax overexpression group, but there was no correlation with overexpression of clusterin or p53. Ki-67 was higher in p53 overexpression group, but there was no correlation with overexpression of clusterin or p53. There was no statistically significant correlation with each other between the overexpressions of clusterin, bax, p53, and Ki-67. The overexpressions of clusterin, Ki-67, p53 was associated with overall patient's survival in borderline significance. CONCLUSION: The overexpression of p53, and Ki-67 were frequent in poorly differentiated ovarian carcinomas. So the overexpression of p53, and Ki-67 can be used as prognostic factor. The overexpression of clusterin was more in epithelial ovarian carcinomas than in borderline tumors but showed no significant correlation with the overall patient's survival. Further studies are required to clarify the possibility of using clusterin for target therapy in epithelial ovarian carcinomas.

The papillary cystadenoma in the scrotum is a rare benign tumor. But papillary cystadenoma needs a observation about stigma of malignant combination. We experienced a case of this, which didn't show the evidence of malignancy. We report this rare tumor.

Billiary cystadenoma and cystadenocarcinoma are rare neoplasms of the biliary ductal system. The authorspresent 2 cases of biliary cystadenoma and 3 cases of cystadenocarcinoma. The typical sonographic apearance ofthese tumors is a large intrahepatic gloular or ovoid thickwalled cystic mass which often containes multipleseptations with papillary growth and solid portion. Low-level internal echoes may be seen within the cystic mass.The characteristic CT findings of these tumors are multiloculated cystic mass, thick sepatations with papillaryprojection sand solid portion within the cystic mass. Angiographical characteristics of these tumors arehypovascular mass with frequent abnormal clusters of tumor vessels within the walls on arterial phase andaccumulation of contrast material along the wall or internal septation on delayed film.
