The primary sarcomas of the brain have been considered rare and occur mostly in infants and children. We report one case of primary sarcoma which was diagnosed as a huze intracerebral honiatoma in the left parietote nporal area with a case history and angiographic findings. Flow ever, the operative findings and histopathological report confirmed a primary sarcoma of the brain belonging to unknown type in. Abbott and Kernohan's classification. The tumor was extended into the leptomeninges and the Virchow Robin spaces, invading the cerebral parenchyma with intracetebral hematoma in the left parieto-temporal area. Dura was not invaded by the sarcoma. This is a case of primary sarcoma arising from the leptomeninges in the brain.

A total of 32 cases of spontaneous intracerebral hematoma caused by hypertension and unknown origin is surgically treated and reviewed. Thirty two cases comprised 22 males and 10 females with a ratio of 2.2 too 1. The age ranged from 30 to 61 years with the highest incidence at 5th and 6th decades. The most important one as to prognosis is the level of consciousness, and the age per se does not influence significantly to the mortality or morbidity. Surgical exploration is better, attempted when the clinical features denote a space occupying lesion.
Identification of Hybrids using SSR markers from Polyembryonic Citrus Breeding Lines

Polyembryony in many citrus varieties is an impediment in breeding because it makes hard to identify hybrids after crossbreeding. So, it has become imperative for developing efficient methods to distinguish zygotic seedling generated from polyembryonic seed depending on citrus variety. Simple sequence repeat(SSR) marker is one of useful systems for such purpose. However, SSR markers to separate zygotic seedlings derived from the crossbreeding between ‘Marita unshiu’ (Citrus unshiu) ‘Seongjeon’ and ‘Shiranuhi mandarin’ [(C. unshiu x C. sinensis) x C. reticulata] ‘Hallabong’ have not been developed yet. In this study we tried to identify an effective SSR marker to screen zygotic seedling after crossbreeding between ‘Seongjeon’ and ‘Hallabong’. For this investigation, 387 seedlings were generated from 114 seeds produced from crossing those two varieties. A total of 116 SSR markers were tested to identify a special marker for distinguishing origin, zygotic or nucellar seedling. As a result, two markers, SSR012 and SSR093, were found to be more effective than other markers. These two SSR markers might be useful to select zygotic individuals in crossbreeing between ‘Seongjeon’ and ‘Hallabong’.

Background: Endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) is currently performed first for the mediastinal nodal staging of non-small lung cancer (NSCLC). However, unsuspected lymph node metastases leading to upstaging are found during the final histopathologic evaluation of surgical specimens. Purpose of our study was to evaluate the characteristics of upstaged lymph nodes and the its effects on survival in patients with NSCLC. Methods: We performed a retrospective review from 2009 to 2019 at tertiary-care academic hospital. Patients who diagnosed NSCLC with post-operative pathologic N2 positive lymph node were included. Nodal upstaging was defined as the unexpected pathological finding of metastasis in N2 nodes in patients who were presumed to have clinical N0 or N1 with preoperative staging. Results: Of 177 patients with positive N2 node postoperatively, overall rate of nodal upstaging was 53.1% (94 patients). The baseline characteristics did not differ significantly between upstaged and unchanged patients. Upstaged patients were more likely to receive adjuvant chemotherapy compared to unchanged patients. Culprit nodes leading to upstaging were subcarinal (38.3%), paratracheal (36.2%), and aortic nodes (21.3%). The size of upstaged node was less than 5mm in EBUS. Threeyear mortality was not different between two groups, but lower rate of mortality was observed after excluding inaccessible lymph node. Progression-free survival was significantly higher in the upstaged patients. Conclusion: Nodal upstaging was mainly attributed to the small mediastinal nodes or aortic nodes that are not accessible by EBUS-TBNA and did not influence three-year mortality. After excluding inaccessible lymph node, even higher survival was found in the upstaged patients than the unchanged patients with the same stage.
LT, Others : PE-131 ; A case of Caroli syndrome in adult

Caroli syndrome is a rare congenital disorder of intrahepatic bile ducts that is characterized by intrahepatic bile duct dilatation and prominent fibrosis in the portal area. In Korea, only 2 cases have been reported in adult age. A 23 year old male visited emergency room for hematemesis. He had received splenectomy for unclear causes several years ago. He didn’t drink alcohol and serologic tests for viral hepatitis were all negative. Liver imaging study revealed multiple intrahepatic large bile duct dilatation with central enhancing dots which acknowledged the presence of Caroli’s disease. Portal hypertension is not common manifestation of Caroli’s disease itself but a major problem when it combined with congenital hepatic fibrosis. Liver biopsy was performed and showed irregular fibrosis containing small bile ducts. He was counseled for the future liver transplantation. We present a rare case of Caroli syndrome confirmed by CT and liver biopsy in adult.

The patent ductus arteriosus (PDA) is a vascular structure connecting the proximal descending aorta to the roof of the main pulmonary artery, near the origin of the left branch pulmonary artery. Transcatheter closure has become the treatment of choice for most cases of PDA in both children and adults; however, measurement of the exact size and morphology of the shunt in adult cases using only contrast fluoroscopy is difficult. We report on a case of a 49-year-old woman who underwent transcatheter closure of PDA with intravascular ultrasound (IVUS) guideance. In the current case, IVUS is feasible and helpful for measuring the exact size and shape of the PDA.
