Hepatoid adenocarcinoma of the stomach has been designated to a primary gastric adenocarcinoma with minimum criteria of elevated serum alpha-fetoprotein and its histological resemblance to neoplastic liver cells. Of the 1,500 consecutive cases of surgically resected gastric carcinomas during a period of 4 years, we retrieved 14 cases of adenocarcinoma which met the histologic features of hepatoid growth and compared them histologically with 400 consecutive cases of non-hepatoid gastric adenocarcinomas. The patient's age ragned from 32 to 80 years(non-hepatoid group: 25 to 81 years) and their male to female ratio was 3.7 : 1(non-hepatoid group: 1.8 : 1). Grossly, five case were Borrmann type II and another five cases type III. All three cases of early gastric carcinomas were the submucosal type IIc. The remaining one was an advanced gastric carcinoma mimicking early gastric carcinoma. Microscopically, the hepatoid portions varied in growing patterns and arranged in either compact, trabecular or pseudoglandular pattern and gave an immunoreactivity to alpha-fetoprotein and alpha-1-antichymotrypsin. Regardless of the tumor stage, the hepatoid areas were located in the deeper portion of the tumor mass and grew in an expanding/nodular pattern. The associated adenocarcinomatous areas were mostly papillotubular, moderately to well differentiated, and frequently revealed clear PAS-negative cytoplasm reminiscent of the differentiated embryonal carcinoma. Tumor emboli and nodal metastasis were the frequent associations. We assume that the hepatoid adenocarcinoma may develop from gastric'adenocarcinoma through embryonal carcinomatous growth.

It has been well known that liver cirrhosis, regardless of its etiology, is an important predisposing factor in hepatocarcinogenesis. However, the type of cirrhosis in hepatocellular carcinoma(HCC)-bearing liver varies not only by geographic areas but also with the cirteria applied for morphological classification of cirrhosis. To elucidate the relationship between the nodule size of HCC-bearing cirrhotic liver and clinicopathologic features, we measured cirrhotic nodule areas of 49 surgically resected HCC cases using image analyzer. The morphological type of cirrhosis was predominantly macronodular(49%), and followed by mixed(37%) and micronodular(14%). Seventy percent of the cases showed seropositivity for HBsAg. The average area of cirrhotic nodules was significantly larger in HBsAg-positive cases(mean: 6.14 mm2) than that of HBsAg-negative cases(mean: 2.5 mm2)(p<0.05), and their size was bigger in cases with grossly expansile pattern of HCC than those cases with infiltrative ones(p<0.05). Based on the above findings, we assume that seropositivity of HBsAg may influence on the regenerative activity of cirrhotic nodules and also subsequent increase of risk for further development of HCC. The presence of cirrhohsis and nodule size seem to be the important contributing factors to determine the growing patterns of HCC.

We present herein a case of sebaceous hyperplasia in a 55-year-old male, who showed multiple asymptomatic yellowish papules on the forehead and the cheeks. Histopathologic examination of a papule revealed numerous sebaceous lobules grouped around several enlarged sebaceous ducts. Three weeks of oral administration. of isotretinoin 40 mg per day brought marked improvement.

We experienced three cases of non-giant congenital nevus. They showed zosteriform or heart-shaped grouping of pigmented papules which were pierced by hairs. Histopathologic examination disclosed nevus cell infiltration in and around hair follicles and in the upper two thirds of reticular dermis. We would like to report these cases as follicle-centered spotted grouped pigmented nevi.

5.Early Gastric Carcinoma with Hepatoid Differentiation: Report of a case with histotopographic analysis.

A 56-year-old man received subtotal gastrectomy for an early gastric carcinoma type IIa+IIc with submucosal invasion. The tumor was made up of mixed papillo-tubular adenocarcinoma and solid carcinomatous portion, the latter comprising approximately four-fifths of the total tumor mass. The solid portion was confined within the submucosa and revealed a mixture of trabecular, compact and pelioid patterns of large polyhedra cells, resembling hepatocellular carcinoma of the liver(Edmondson-Steiner grade 2). Sinusoid-like vascular stroma of classical trabecular hepatocellular carcinoma intervened the tumor cell nests but was not associated with endothelial-cell lining. Immunohistochemical stainings with alpha-fetoprotein and alpha1-antitrypsin gave a strong reactivity in those areas of hepatoid differentiation and in the adjacent minute portion of adenocarcinoma. The findings suggest that a portion of gastric carcinoma may transdifferentiate into cells with hepatoid features along the line of endodermal lineage.

6.Mesenteric Cystic Lymphangioma with Sustained Abdominal Pain : Report of a case.

A case of cystic lymphangioma of the mesentery with severe and persistent abdominal pain in a 22-year-old man is presented. The cyst was filled with chylous fluid. Microscopically, numerous nerve bundles were incorporated within the lymphangiomatous walls, and some protruded into the lumen. The above findings lead to a suggestion that mesenteric lymphangioma may differ from those in the other sites by its abundance of incorporation of nerve bundles into the lymphangiomatous walls, and that increase of tumor size by intracystic accumulation of chylous fluid may subsequently result in increase of intraluminal pressure to compress the nerve bundles with which abdominal pain is much enhanced.

7.Hematic cyst formation after repair of blow-out fracture.

Alloplastic implants are known to be inert for many years, though complications are infrequently reported many years after their insertion. We report the case of a patient who had undergone a blow-out fracture repair five years before the discovery of a hematic cyst. He had been free of symptoms for the first five years after his orbital floor repair but then developed pain on eyeball movement and persistent vertical diplopia, which finally led to surgical intervention. At surgery, a hematic cyst was found to have formed around the implanted silastic plate. When alloplastic material is used in orbital fracture repair, we should be alert for late complications which may occur many years after surgery.

Tarsometatarsal injury has not been paid much attention due to it is unusual frequency. But the cases of tarsometatarsal injuries are on the increase in proportion to the increasing "high energy trauma injury" resulted from the traffic and industrial accidents. The purpose of this study is both assessing the relative effects among clinical results, final radiologic findings, treatment results and symtoms. In view of the results so far achieved from 20 cases of tarsometatarsal fracture dislocation which had been treated at Sung-Ae general hospital from January 1990 to December 1993, the results were as follows: 1. Thirteen cases were treated by open reduction and 3 cases were treated by closed reduction with smooth pins but no reduction loss were experienced. 2. Traumatic arthrosis could be observed in 14 cases but there were no influences on the functional end results. 3. Anatomical results correlated with pain. 4. Anatomical or neraly anatomical reduction was considered as most important factor of prognosis.

If one can measure the actual angle of the bowing and rotation of a long bone three-dimensionally, it will be a great help in fracture reductions, operative treatments of the congenital snomalies, determination of the fusion angles in arthrodeses, and so on. We developed a computer program that gives us the actual bowing and rotation angle when we input the angles from the two X-ray films with known angle between them. We measured anteversion and neck-shaft angle of the femur, the amount of bowing and rotation in fracture model, and the fusion angles in arthrodeses. The angles calculated from the computer program were same as those from another X-ray that showed the actual angle taken by derotating the subject.
