The morphologic development of the liver in the embryonic period is described in serial sections of 18 human embryos representative of Horizons 12 to 23 . In the earliest specimen of horizon 12, the liver is seen as branching cord of endodermal cells originating from the hepatic diverticulum and invading into the loose stroma of septum transversum, transforming the surrounding stromal cells into primitive blood spaces and blood cells. Thereafter, the parenchymal cells rapidly proliferated so that the size of the organ was reaching a fifth of the CR length in horizon 23. The vascular system of the liver was in a symmetric configuration in horizon 12, which is composed of umbilical and vitelline veins and hepatocardiac channels on both sides. The evolution of the vascular system includes intergration of the vitelline veins into the portal vein, obliteration of the right umbilical vein and left hepatocardiac channel, and creation of the ductus venosus. The intrahepatic biliary tract is found to be formed by the "in situ transformation" mechanism, which involves transformation of the parenchymal cells, adjacent to the fibrous tissue surrounding the portal and umbilical veins, to networks of cuboidal epithelial cells lining the ductal lumen. These intrahepatic duct systems were found to communicate with the extrahepatic system at the porta hepatis.

Omental cyst is benign unilocular or multilocular endothelium-lined cyst that contains either chyle or serous fluid. They are uncommon yet interesting intraabdominal masses that may be difficult to diagnose clinically and often are missed on abdominal palpation. The etiology of this lesion has been subject to much discussion in the literature over the years with the principal debate centering around the question of whether or not this lesion is congenital. It is now recongnized that there is no single etiologic mechanism involved in the development of this lesion. Recently we have experienced an autopsy case of omental cyst occurring in a male fetus. Pregnancy was artificially interrupted at 28 weeks gestation due to suspicious mesenteric cyst or fetal ascites on ultrasonography. Postmortem examination showed hydrops fetalis, hypoplasia of the lungs, ad multifocal calcifications of myocardium. There was an omental cyst in the greater omentum which was 7x3 cm in size, unilocular and containing clear, straw-colored fluid and proteinacious core without evidence of bleeding or calcifications. Microscopic examination of this cyst showed cuboidal or flattened mesothelial lining cells and underlying loose fibrovascular connective tissue with discrete lymphocytic collections. Rarity and interest on the pathogenesis made us redport this case.

Somatostatin secreting islet cell adenoma(somatostatinoma) of the pancreas is a rare entity. Less than 30 cases of pancreatic somatostatinoma could be searched in the world literature. We present a case of somatostatinoma of the pancreas in a 64-year-old woman. This patient had suffered from diabetes, cholelithiasis and intermittent diarrhea. Laboratory examination revealed steatorrhea, blood somatostatin level of 30 pg/ml, and fasting blood glucose level of 116 mg/dl. Subtotal pancreatectomy was done after radiological demonstrations of a round tumor mass in the pancreas. It was a 2 cm-sized well demarcated yellowish brown round solid mass located in the proximal pancreas. A retention cyst was seen just distal to the tumor. Histologically, tumor masses consisted of polygonal cells with distinct cell border, having granular eosinophilic cytoplasm and small bland looking nuclei. The tumor cells were arranged in small solid islands and trabeculae, separated by fibrovascular stroma. Immunohistochemical stain for somatostatin was positive in the cytoplasm of the individual tumor cell, and ultrastructurally variable sized membrane bound electron dense granules of 200 nm in average diameter were found in tumor cells.

Nodular fasciitis is a rare and benign soft tissue tumor that can easily confused microscopically to spindle cell sarcoma. Therefore it is very important disease to the surgical pathologists. However, this lesion has been seldom reported or described in Korean literature. This paper deals with 13 Korean cases of nodular fasciitis diagnosed microscopically. It's pertinent clinicopathologic findings are described. The youngest patients among 13 cases was 18 years and the oldest was 63 years with the mean of 34 years. Nine were males and 4 were females. Pathologically, the size of the lesion at the time of diagnosis ranged from 0.7 cm to 4.0 cm in the maximum extent. Two were smaller than 1.0 cm and 8 cases were between 1.0~3.0 cm. The site distibution was; trunk(5) upper extremitiy (4), lower extremity (2) and head (2). All the lesions were located in the subcutaneous tissue. The history of recent rapid growth was noted in nearly half of the cases. Mass and tenderness were two common manifestations. In one case, multiple nodules were found in the right breast and in flank. All of the lesions except one were managed by local excision. In one case, a wide excision was done under the impression of malignant fibrous histiocytoma of frozen section. Follow up observation of all cases did not show any evidence of recurrence in all.
