Primary carcinoid tumor of the kidney is extremely rare ; only 29 previous reports have been described in the world literature, 3 cases of which were known to arise in horseshoe kidneys. Because of the scarcity of primary renal carcinoid tumor, its clinicopathologic features and prognosis are not well characterized, and its histogenesis is unknown. We present a case of primary carcinoid tumor arising in the horseshoe kidney of a 43-year-old man. The lesion is morphologically identical to those of gastrointestinal or respiratory tracts. In addition, this tumor contains clusters of intestinal epithelium with goblet cells and mature bony trabeculae. The cytoplasm of the tumor cells are immunoreactive for keratin, NSE, and synaptophysin, but are negative with Grimelius and Fontana-Masson stains. Membrane-bound cytoplasmic neurosecretory granules are observed by electron microscopic examination. This is the first case of primary renal carcinoid tumor arising in a horseshoe kidney documented in Korea. We describe the gross features, light and electron microscopic, and immunohistochemical findings of renal carcinoid and review the literature, with speculations on the possible histogenesis of this unusual neoplasm.

Epithelioid smooth muscle tumor is relatively rare and potentially malignant, especially in retroperitoneum. Distinct criteria for malignancy still have not been clarified in this epithelioid variant arising in retroperitoneum. We report a deceptively benign-appearing epithelioid leiomyosarcoma in a 50-year-old female. She was admitted with abdominal discomfort and dysuria. Abdominal CT showed a well-demarcated, 10 10 cm sized, solid mass in retroperitoneum. Concomitant metastatic lesions were noted in right lung field. Surgical excision of retroperitoneal mass and right lung lobectomy were performed. The retroperitoneal mass showed yellowish-tan, well-delineated and lobulated appearance. Histologically, this tumor was composed of predominantly epithelioid, round to oval cells with distinct clear cytoplasm and slightly atypical nuclei. Mitosis was rare (0~1/50 HPF). Lung lesions were morphologically similar to that of retroperitoneum.

Epithelioid hemangioendothelioma of liver is a very rare tumor of vascular origin, the most peculiar feature of which is that it is composed of endothelial cells closely resembling epithelial cells. We present a primary epithelioid hemangioendothelioma of liver in a 40-year-old male. This tumor was composed of an ill-defined yellowish white, 7 x 4cm sized, firm, solid mass and small satellite nodules in the right lobe of liver. Microscopically, two types of tumor cells-dendritic and epithelioid-were identified. The neoplastic cells infiltrated into sinusoids and intrahepatic veins. The background of tumor showed marked sclerotic change and focal proliferation of bile ductules. Confirmation of the endothelial origin of these cells was provided by positive immunoperoxidase staining for factor VIII-related antigen, and by electron mi-croscopic demonstration of Weibel-Palade body. This is the first case of epithelioid heman- gioendothelioma of liver documented in Korea. We report this case in view of its scarcity and distinctive morphologic features that allow differentiation from sclerosing carcinoma and angiosarcoma.

BACKGROUND: Cold blood cardioplegic solution has been used to protect myocardium during open heart surgery with the hypothesis stating that it provides more oxygen supply to myocardium compared to crystalloid caridoplegic solution. We repeatedly infused cold blood cardioplegic solution to achieve myocardial protection. We biopsied a small portion of papillary muscle of patients with mitral valve replacement or double valve replacement during aortic cross-clamp time and evaluated the method of myocardial protection through the observation of changes in ultrastructure. We then analysed the relationship between changes in ultrasructure and peak postoperative CK-MB value and SGOT value. MATERIAL AND METHOD: We report observation on changes of myocardial ultrastructure, postoperative CK-MB and SGOT, and electrocardiogram in 31 patients who underwent cardiac operation. There were 11 males and 20 females, and they ranging in age from 28 to 69 years (mean score was 2.08+/-0.560, it was 2.37+/-0.558 at 40 minutes, and it was 2.36+/-0.523 at 70minutes. Mitochondrial score increased significant at 40 minutes. Mean value of postoperative peak CK-MB and SGOT were 37.3+/-17.061IU, 144.5+/-125.5IU respectively. We were not able to find any new Q were in EKG after the operation. There was no significant relationship between myocardium mitochondrial score and mean value of postoperative peak CK-MB and SGOT. CONCLUSION: In conclusion, with this study the cold blood cardioplegic solution was incomplete in preserving ultrastructure of myocardium even with satisfactory results in serum enzyme and EKG evaluation.

Of the more than two hundred collections of pildamchanghwa scattered around the world that are being catalogued and translated, more than forty are medical in nature. This paper organizes and charts the medical written conversations by their dates of publication and examine the various aspects of their publication. Medical written conversations have been collected since the Fourth Envoy. There are no records of medical written conversations or poetry exchange in Tsushima even though that was the first port of arrival for the Tongsinsa. Instead, sources show that written conversations and poetry exchanges mostly took place in Kyoto, Tokyo, and Osaka; indeed, these three cities, in that order, also have yielded the highest volumes of publication. The first commercially published collection of medical written conversations was Sanghaneuidam, published in 1713 following the Eighth Envoy. Though Gyerimchanghwajip was published two years earlier in 1711, it is clear from the usage of the word changhwa in the title that this collection was not strictly limited to medical written conversations. Sanghaneuidam was an attempt by Japanese medicine to collect questions and answers in order to publish as medical textbooks. The Japanese medicine that was involved in the most written conversations was Kawamura Shunko, who was the editor of Sanghaneuimundap and Joseonpildam following the Tenth Envoy. Publications with titles containing 'eui' explicitly contemplates the targeted readership. Kitao Shunpo was one Japanese medicine who was less interested in meeting a literary scrivener, but instead sought to converse with a respected medicine. When the Eighth Envoy of 1711 arrived in Ogaki, Kitao followed around the Joseon medicines and attempted written conversations. He enlisted the aid of his second son Shunrin in organizing the written conversations, and published the collection, complete with preface, postscript, and appendices-an editorial decision that fully contemplated his audience. Prior to meeting Gi Du-mun, Kitao meticulously planned out the order of questions-that is, the table of contents for Sanghaneuidam. Kitao drafted his questions to serve the purpose of a medical textbook, edited the contents of the written conversations, and added illustrations before presenting the collection to the public. Seomulyuchan, one of the most famous leishu in Japan, contains a preface by Lee Hyeon, a scrivener of Joseon. Kitao, who had studied Dongeuibogam, had already possessed a vast and systematic knowledge of materia medica; however, he sought Lee's contributions, hoping that a preface written by a renowned Joseon scholar would lend his publication more credibility. As such, it can be inferred that the preface to Seomulyuchan was created as an extension of the medical written conversations.

Cervical pregnancy is a rare form of ectopic pregnancy and it can cause life-threatening bleeding. Until recently abdominal hysterectomy has been considered the standard therapy for fear of profuse hemorrhage. Methotrexate, however, can be useful agent to conserve further fertility and it is used in various routes of administration. We report a case of cervical pregnancy that was successfully treated by intraamniotic methotrexate injection under the guidance of transvaginal ultrasonography and subsequent four systemic doses thereafter.

Although the diagnosis of primary tuberculous peritonitis in pregnancy is seems challenging because of protean manifestations and difficult surgical intervention, prompt diagnosis and treatment can minimize both maternal and fetal/neonatal mortality. We have experienced one case of this disease in 23-year-old primigravida in 24 weeks of gestation.
