PURPOSE: To assess the utility of color Doppler sonography in the differential diagnosis of thyroid nodules. MATERIALS AND METHODS: Fifty patients with thyroid nodules(10 cases of follicular adenoma, 12 of adenomatous hyperplasia, 21 of papillary adenocarcinoma, and 7 of follicular adenocarcinoma) were analyzed. Colour signal analysis was performed by inspecting the signals in and around the nodules, and these were graded from 0 to III according to the degree of vascularity in internal and marginal blood flow. Peak systoic velocity (PSV) and resistive index (RI) in internal vascularity were used to analyse the flow signal. RESULTS: Internal colorsignals of malignant lesions tended to be high grade, whereas those of benign lesions tended to be low grade, with statistical significance(P<0.05). In spectral wave analysis, correlation between PSV and malignancy of thyroid nodules was statistically significant(P<0.05). The value of RI did not correlate with the malignancy of nodules, but tended to show a meaningful difference. CONCLUSIONS: Although further studies may be required, color Dopplersonography using color signal analysis and flow signals analysis is a useful imaging modality for the differentiation of benign and malignant lesions of thyroid nodules.

Endometrial papillary serous carcinoma (EPSC) is a distinct variant of endometrial adenocarcinoma that histologically resembles ovarian serous papillary adenocarcinoma and has an aggressive clinical course. Usually, the tumor is diagnosed at the advanced stage. The tumor has well confused with metastatic ovarian tumor of identical histology. Diagnosis of EPSC should be considered when the cervico-vaginal smear reveals numerous papillary clusters of tumor cells with macronucleoli and psammoma bodies. Recently, we have experienced two cases of EPSC diagnosed on cervico-vaginal smears, which revealed characteristic cytologic features including numerous papillary clusters of tumor cells with macronucleoli. The cytologic diagnoses were confirmed on histologic sections.

Familial adenomatous polyposis (FAP) includes early development of up to thousands of colorectal adenoma and of colonic adenocarcinoma in all untreated cases. Moreover, a variety of extracolonic manifestation are seen. Several reports have demontrated a high incidence of papillry carcinoma of thyroid. We experienced a case of familial adenomatous polyposis, presenting with thyoid papillry carcinoma, and reported with a brief review of literatures.

Biliary papillomatosis (BP) is an extremely rare condition that's characterized by multicenteric proliferations of adenomatous epithelium within the large bile ducts. Although BP is basically a collection of benign papillary adenoma, papillary adenocarcinoma can develop within these lesions, and it has a tendency to spread supericially along the bile duct mucosa. Such a malignancy is rare, but the prognosis is poor if it is impossible to completely remove the tumor. We report here on one case of multiple biliary papillomatosis in the biliary tree.

A histological study on gastric cancers was carried out on 452 gastric cancers diagnosed at K hospital. The results: (1) Gastric cancers are commonest at the age 61-70, the male/female rate is 1.38. (2) The great majority of gastric cancers are gastric carcinomas (96.68%) with the highest rate of tubular adenocarcinoma (56.16%) and most of these cases are highly differentiated (40.24%); stromal tumors and malignant lymphomas are very rare tumors (1.55% for each type); Non mucinous carcinoma rate is higher than that of mucinous carcinoma rate is higher than that of mucinous carcinomas (94.47% vs. 5.53%). (3) Immunohistochemical is very useful in the diagnosis of small cell carcinomas, one neuroendocrine tumor, one c-kit mutation gastrointestinal stromal tumor (Cajal cell tumor) and three gastric T cell lymphomas. The significance of the data was discussed.

OBJECTIVES: The thyroid disease is the common form of endocrine diseases, which often requires surgical management. Recently, fine needle aspiration biopsy is widely used preoperatively. As a result, some studies show that numbers of thyroid operation have decreased significantly. We performed this study to analyze the clinical features of thyroid diseases and the trend of thyroid operation in Korea. METHODS: We reviewed medical records of 1787 cases with thyroid diseases who were managed surgically in Catholic Medical Center, Korea from 1988 to 1992. RESULTS: 1) The percentage of thyroid diseases in total cases undergoing operation in Department of General Surgery was 3%, which tended to decrease with time.2) 72.9% of thyroid diseases was benign. Among them, the frequency of nodular hyperplasia and follicular adenoma were 67.5% and 18.4%, respectively.3) The percentage of thyroid cancers in thyroid diseases was 27.1%, which tended to increase with time. The frequency of papillary adenocarcinoma was 78.6%, follicular adenocarcinoma 18.2% and medullary carcinoma 1.5%.4) Thyroid cancers were most commonly found in the forty and sixty decades. Male:female ratio was 1:8.5.5) 7.6% of thyroid cancers was accompanied by benign thyroid diseases which were mostly nodular hyperplasia and follicular adenoma.6) The most common type of operation was lobectomy (82.5%) in benign thyroid diseases, and total thyroidectomy (47.1%) and lobectomy (41.1%) in thyroid cancers.7) Fine needle aspiration biopsy was performed in 51.7% of thyroid nodules, the frequency of which tended to increase with time. The sensitivity, specificity, false negative rate and false positive rate of this test were 78.3%, 89.4%, 13.7% and 17.2%, respectively. CONCLUSION: With the use of fine needle aspiration biopsy, numbers of thyroid operation decreased and the percentage of thyroid cancers in thyroid operation increased.
