Meigs' syndrome is defined as a hydrothorax with ascites and a pelvic tumor, both of which resolve on removal of the tumor. Pseudo-Meigs' syndrome is a variant not possessing the original tumor cell types described by Meigs. Both these syndromes should be considered in otherwise healthy women who present with either new or recurrent hydrothorax and ascites. Pseudo-Meigs' syndrome occurs with the clinical triad of (1)ascites, (2)pleural effusion and (3)Brenner tumors, struma ovarii, benign thecomas, extreme ovarian edema, uterine leiomyomas or other benign pelvic tumors. A case of Pseudo-Meigs' syndrome associated with Brenner tumor is presented with a brief review of literatures.

Background: Fine needle aspiration and biopsy(FNAB) has known the most accurate test(about 90%) in the preoperative evaluation of patients with a thyroid nodule. The false negative findings of thyroid cancer by FNAB are mainly due to the aspiration of cystic fluid in cystic degeneration of thyroid cancer and the ipossibility of differentiation between follicular adenoma and carcinoma by aspiration or FNAB because of the failure to evaluate the capsule invasion or angioinvasion of the tumor. Actually more than 80% of the nodules are found as benign nodules in aspiration or FNAB and the findings of follieular lesions are found about half of the samples tested, so limiting the cancer incidence in surgically resected samples up to 50% of the surgical resection. Sa reasonable guidelines to manage the benign nodules on aspiration or FNAB are needed which can select the maligna~nt nodules with false negative findings on aspiration or FNAB. We tried to evaluate whether the thyroxine suppression therapy can increase the malignancy rates on thyroidectomy, Methods: We treated the benign thyroid nodules in FNAB with thyroxine for 1 year and cornpared the nodule volume change before and after treatment (every 6 month) with ultrasonogram. We performed thyroidectomy on 1~7 thyroid nodules wbich showed less than 50% decrease of nodule volume after 1 year of thyroxine suppression therapy. Results: The results were as follows. 1) Of all 17 patients, surgical resection revealed malignant thyroid nodule(Group I) in 10 cases (58.82%, papillary cancer. 6 cases, follicular cancer: 4 cases) and benign thyroid nodule(Group II) in 7 cases(41.18%, follicular adenoma: 4 cases, adenomatous goiter: 3 cases). 2) Between group I and II, there was no significant differences in serum T, T and TSH levels before and after thyroxine suppression therapy. Also, there were no significant difference in TSH suppression % between group I and group II(5.60+5.39%, 14.64+11.48%, respectively). 3) Thyroid nodule volume decrease percent before and after thyroxi~ne therapy showed no significant difference between group I and group II (124.80+54.18% vs 159.42+79.82%, p>0.05). Conclusion: Our data suggested that the benign thyroid nodules on aspiration or FNAB which were not suppressed in volume after thyroixine therapy revealed more than 50% incidence of malignancy on surgical resection, so these nodules were highly reeommended to surgical exploration.

An attempt has been made to discriminate synaptic diversity in the neostriatum of the cat with emphasis on the characteristic structures of axon terminals and postsynaptic profiles. The differentiation of the axon terminals was based on the size and shape of synaptic vesicles in the axoplasm. Three types of axon terminals could be differentiated: Type I, the terminals contained small round (45 nm in diameter) vesicles; type II, the terminals with large pleomorphic (50 nm) vesicles; and type III, the terminals contained flattened (45 x 25 nm) vesicles. The type I terminals were making asymmetrical or symmetrical synapses in contact with the somata, dendrites and dendritic spines of neurons in the neostriatum, and a few type I terminals making asymmetrical or symmetrical contact with axons were also observed. The type II and III terminals were making symmetrical contact with the somata and dendrites of neostriatal neurons. A few type II terminals formed at the node of Ranvier of myelinated nerve fibers were making symmetrical contact with large dendrites. Additionally, dendro-dendritic and serial syanpses were rarely found in the neostriatum. In the serial synapses composed of axo-dendritic and dendro-dendritic synapses, the type I terminals making asymmetrical contact and the type II making symmetrical contact were identified.

In our study we estimated mitral orifice area by use of two dimensional echocardiography in 59 patients with mitral stenosis form February 1979 till June 1981. We classified them to 3 subgroups by severity of mitral stenosis as Cope was done in 1975. and investigated correlationship between the severity and other various echo-cardiographic findings indices such as mitral valve calcification, posterior mitral leaflet motion, doming of mitral valve, EF slope, ED amplitude, LA dimension, LA/Ao ratio and especially mitral valve closure index. The following results were obtained. 1) We could accurately estimate mitral orifice area by two dimensional echocardiography. 2) Except EF slope and MVCI, we could find that various echocardiographic findings were poorly correlated with mitral orifice area measured from two-dimensional echocardiography. 3) MVCI was overlapped less frequently than EF slope in severe, moderate and mild mitral stenosis, and we could find that MVCI reflected the extent of mitral stenosis more accurately than EF slope.

PURPOSE: Gastrointestinal stromal tumors (GISTs) are of a mesenchymal origin, and they arise predominantly from the gastrointestinal tract. This study aims to aid the post operative management of GIST patients by analyzing the clinical and immunopathological features of recurrent GISTs. METHODS: We enrolled 98 GIST patients who had been operated on for their primary tumor from 1987 to 2001 at the Catholic Medical Center. Among them, 28 patients had clinical and radiological features that were proved to be recurrence, and the patients' survival rates were compared according to the treatment modalities. RESULTS: When the maximum length of tumor was shorter and the mitotic index lower, then these patients had higher disease free survival rates and lower recurrence rates. The Ki-67 negative group had lower recurrence rates than their Ki-67 positive counterparts. Recurrence was mostly observed as liver metastasis. The mean length of time to recur was 22.96 months. Fifteen patients received additional treatments such as surgery, chemotherapy and radiation therapy, but there was no significant difference in survival rates when they were compared to the 13 patients who did not receive further treatments. CONCLUSION: Of the patients diagnosed with GIST after surgery, those with worse prognostic factors, i.e. a bigger tumor size and higher mitotic index, require more meticulous surveillance for tumor recurrence, and especially for liver recurrence, which was the most common recurrence site, during the follow up exams. In addition, although there have not been any remarkably effective treatments for the recurrent GIST patients, further researches for new therapy such as STI-571 is mandated.

A gastric adenocarcinoma is the second most common cause of cancer deaths worldwide, but there are some geographical differences in its incidence. A gastrointestinal tumor is an uncommon disease with a wide spectrum of aggressive behavior. These two tumors have a distinct pathogenesis, and synchronous occurrence of an adenocarcinoma and a GIST (gastrointestinal stromal tumor) in the stomach is very rare. We report a case of synchronous occurrence of a gastric adenocarcinoma and GIST in a 64-year-old man. We performed the following tests: barium swallowing test, gastroduodenoscopy, and CT scanning. We performed a total gastrectomy, and a 9 cm-sized GIST at the fundus and a small early gastric cancer at the antrum were confirmed pathologically. Some explanations for this rare case exist, but in our opinion, the synchronous occurrence is a rare but probable event that can happen in an endemic area. We describe a case of synchronous occurrence of a gastric adenocarcinoma and GIST in the stomach, with a review of the literature.

Hypereosinophilic syndrome (HES) is characterized by chronically increased peripheral blood eosinophil levels and organ damages related to eosinophilic infiltration. Cutaneous manifestations are common (>50%) and non-specific. It is generally manifested as erythematous pruritic eczema. Linear lichen planus has not been reported in HES. A 35-year-old woman was presented with linear brownish papules and plaques on her left arm. She had been diagnosed with HES three years earlier. Initially, the skin lesions were manifested as linear pruritic erythematous plaques, but they gradually transformed into shiny brownish plaques. Skin biopsy specimens showed irregular acanthosis of the epidermis and band-like infiltrations of lymphocytes and eosinophils with necrotic keratinocytes in the papillary dermis. We proposed that the eosinophil infiltration was caused by HES, and that the patient's histological and clinical manifestations should account for linear lichen planus.

A 69-year old man presented with severe epigastric pain for 1 day. He had early gastric cancer at the antrum and underwent a distal subtotal gastrectomy and Billorth II gastrojejunostomy one month later without any post-operative complications. Radiologic examination revealed a large amount of retroperitoneal free air formation. Because of unremitting pain and unstable vital sign, exploratory laparotomy was followed. During the operation, a perforated duodenal diverticulum at the posterior wall of the 2nd portion of the duodenum was identified. He underwent diverticulectomy and primary closure. He was discharged on the 18th post operative day and has been followed up without any evidence of comlpication for several months.
