Stomach cancer is the most common malignant neoplasm among Korean men and considered as one of the most important malignant disease in many countries. Thus, many studies have been established about factors affecting prognosis of stomach cancer. These include studies of histopathological pattern which were performed by Mulligan and Rember (1954), Lauren (1965), Ming (1977), and Teglbjerg and Vetner(1977). The present study is aimed to evaluate the useful factors to predict the prognosis of patient of stomach cancer in relation to the histopathological patterns. The material consisted of 284 cases which were diagnosed as gastric carcinoma at the Department of Pathology, Yonsei University, College of Medicine from January, 1981 through December, 1982. After the classification of gastric carcinoma by Ming (1977), Willis (1967), and Mulligan and Rember (1954), age and six of the patients, histopathologic patterns, depth of invasion, degree and major component of inflammatory reaction, lymphatic permeation and metastatic incidence to the regional lymph nodes were investigated, and the results obtained were as follows; 1) The overall male to female ratio was 1.4 : 1 and mean age was 51.6 years old. The mean age of patients with EGC was 46.8 years old, while that of patients with invasive cancer was 52.2 years old, indicating about 5 years difference. 2) The classification of 284 cases by Ming's method showed 36.3% of expanding type and 63.7% of infiltrative one. The incidence of metastasis to regional lymph nodes was 58.3% in expanding type and 72.4% in infiltrative one. 3) The classification of 284 cases by Willis' method showed 45.8% of adenocarcinoma and 23.2% and of signet ring cell carcinoma. Adenocarcinoma anaplastic carcinoma had high degree of desmoplasia. Among them, moderately well differentiated adenocarcinoma and anaplastic carcinoma showed markedly lower metastatic rate to regional lymph nodes than others. 4) The classification of 284 cases by Mulligan and Rember's method showed 15.1% of intestinal cell carcinoma, 21.5% of pyloro-cardiac gland cell carcinoma and 61.6% of mucous cell carcinoma. Highly differentiated intestinal cell and pylorocardiac gland cell carcinomas and desmoplastic mucous cell carcinoma had high degree of desmoplasia. Among them, highly differentiated intestinal cell carcinoma and desmoplastic mucous cell carcinoma showed markedly low metastatic rate to regional lymph nodes. 5) Adenocarcinoma with good differentiation showed higher mean age and male predominancy in comparison to carcinoma with poor differentiation. 6) The degree of inflammatory reaction did not show significant difference in relation to the patterns of gastric carcinoma and the rate of regional node metastasis. However, according to the cell types involved in inflammatory reaction, plasma cell-predominant inflammatory reaction showed low metastatic rate to regional lymph nodes. 7) The more the degree of desmoplasia was observed, the less the rate of metastasis to regional nodes was noted and the difference was statistically significant. 8) The rate of metastasis to regional nodes showed marked difference by the depth of cancer invasion; confined to mucosa, 0% : to submucosa, 15.4%; to muscular layer, 66.7%; and to serosa and perigastric area, 76.5%. In summary, the results of this study indicated several factors suggesting good prognosis, such as; (1) expanding growth pattern, (2) good differentiation, (3) high degree of desmoplasia as stromal reaction, (4) plasma cell-predominant infiltration, and (5) lesser deep invasion. These factors were better evaluated by Mulligan and Rember's classification.

We report a case of an uncommon cutaneous neoplasm of nerve sheath myxoma in a 25-year-old woman who had a papule on the left cheek of her face. The histologic findings of the lesion showed that lobulated tumors were composed of spindle shaped and stellate tumor cells in an abundant matrix of mucosubstances. The electron microscopic findings showed numerous cytoplasmic myelin figures, and interdigitating long cytoplasmic processes. 5-100 protein was not discovered and alcian blue and PAS stain showed positive. After surgical excision of tumor, the patient did not have any evidence of disease for one year.

BACKGROUND: Various surgical techniques are used for the cure of hemorrhoid according to the extent of disease and severity of symptom. Purpose : We compared the postoperative clinical course after submucosal hemorrhoidectomy and ligation and excision of hemorrhoids. MATERIAL AND METHODS: Between February 1995 and May 1997, 221 patients underwent submucosal hemorrhoidectomy and 111 patients underwent ligation and excision of hemorrhoids at the Department of Surgery, Eulji General Hospital. We compared the hospital course and postoperative complications in two group. RESULTS: For submucosal hemorrhoidectomy group, mean operation time was 38 minutes, the improvement of postoperative pain, is based on no needs of analgesics after 48 hours of postoperation, was seen in 115 patients(52.0%), wound healing took 19.5 days in average, and mean hospital stay was 6.4 days. For ligation and excision group, these findings were mean operation time 21 minutes, the improvement of postoperative pain in 47 patients(42.3%), wound healing 25.4 days, and hospital stay 7.2 days. Postoperative complications such as skin tag, edema, and were more common in submucosal hemorrhoidectomy group. But anal fissure, stenosis were more frequent in ligation and excision group, although they did not occur later. CONCLUSION: We think that submucosal hemorrhoidectomy is a better method than ligation and excision in respect of postoperative course and complications.

Mediastinum is bounded by sternum, vertebra, 1st rib, and diaphragm externally, and by pleural cavity internally and includes important structures such as great vessels, nerves, thymus and many lymph nodes. Primary and metastatic cancers, cysts and inflammatory lesions can develop in this region, and the tumor developing in the mediastinum has a tendency to developed in a specific area of mediastinum depending on the histologic type. Therefore the developing site of tumor and the clinical findings are very important in diagnosing the tumor of the mediastinum. We studied not only the characteristics of mediastinal tumor and tumorlike conditions but the histologic classification and frequency of mass to a specific area and then observed if there is any information that could help in diagnosis of the lesion of the mediastinum. Results obtained were as follows: 1) Of the 95 cases of mediastinal lesion which excludes inflammatory process, there were 70 cases (73.5%) of primary tumors, 13 cases (13.1%) of metastatic tumors and 12 cases (12.6%) of tumor-like conditions. 2) Of the 70 cases of primary tumor, 54 cases (76.8%) were benign, 13 cases (20%) were malignant and 3 cases were unclassified or unidentified tumor with the overall 3.8:1 prevalence rate of benign tumor compared to malignancy. 3) Histologic classification of the 70 cases of primary tumor showed 27 cases (28.4%) of germ cell tumor, 22 cases (23.2%) of neurogenic tumor, 7 cases (7.4%) of thymoma, 6 cases (6.3%) of lymphoma and 5 cases (5.3%) of soft tissue tumors with the highest frequency of germ cell tumor. Germ cell tumor and neurogenic tumor exceeded to 50% of total primary mediastinal tumor. 4) Male to female prevalence rate showed that benigh tumor had a high frequency in female with the the ratio of 1:1.4. But malignant tumor showed much higher frequency in male with the ratio of 4.2:1. 5) Anterior mediastinum had germ cell tumor, thymoma and lymphoma in order of frequency. Metastatic tumor was the most common in superior mediastinum. Superior mediastinum had germ cell tumor and neurogenic tumor with about the equal number, and soft tissue tumor was also developed. Middle mediastinal tumor was less common in number compared to other portions of mediastinum but the majority of tumors developed was developmental cysts and metastatic tumors. And the majority of neurogenic tumors occured at the posterior mediastinum. 6) Mass sized 5-10 cm in diameter were about 55.7% of all tumor, 2.5-5 cm and 10-15 cm were 20% respectively. But the mass sized smaller than 2.5 cm and larger than 15 cm were about 5% respectively. And the malignant tumors have more larger size than benign tumors. 7) Patient with benigh tumor had no symptoms at all or some complaints of chest tightness, dyspnea, chest pain, shoulder pain and dysphagia. In addition to above symptoms, patient with malignant tumor complained of systemic symptoms such as weight loss and fever.

BACKGROUND: Surgical resection remains the mainstay of treatment for esophageal cancer. Despite recent advances in surgical therapy, i.e. en bloc resection and extended lymphadenectomy, the overall long-term prognosis of patients with esophageal carcinoma has not, however, improved during the last decades. One of the major reasons in its relatively high recurrence rate. MATERIAL AND METHOD: A retrospective review of recurrent patterns of cancer in 42 patients who underwent curative surgery for primary esophageal cancer was performed clinically and histo-phthologically. RESULT: Nineteen patients had developed recurrece during the 18 to 52 months(mean 34.2 nonths), 8 had local recurrences, 1 had both, and 11 had systemic recurrences. Twelve patients(63%) had developed recurrence within 1 year, 5 patients(26%) between 1 year to 2 patients(11%) after 2 years. The recurrence rate according to growth pattern of tumor or presence of microinvasive findings was not statistically significant, but it increased significantly in clinical tumor stage III than stage IIA, B and in patients with the number of metastatic lymph node over ten. CONCLUSION: Post-operative recurrences of esophageal cancer appear as a high rate even though curative wide resection was done. Several clinical and histo-pathological factors correlate with the recurrence.

The rapid frozen section method is a means of intraoperative pathological diagnosis, first introduced by Welch in 1891 and developed as a diagnostic tool by Cullen, Wilson, MacCarty et al. This method serves useful purposes, such as determining the malignancy or benignancy of a suspected lesion, determining the adequacy of a biopsy of a suspected lesion, confirming the presence or absence of metatasis, and identifying small structures. But it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations and the accuracy of the frozen section method and the materials studied was total cases of frozen section during recent 5 years. The ovarall accuracy of the frozen section diagnosis of 1,603 cases was 96.2% with 0.3% of false positive, 3.5% of false negative and 2.8% of incorrect histological diagnoses or grading errors the tissues submitted for frozen section were lymph node, breast, gastrointestinal tract and soft tissue in decreasing order of frequency. The false positive cases were four in number, while the false negative cases were 53, one third of which were the misdiagnoses of the presence of ganglion cells in Hirschsprung's disease.

There have been controversies on the rationale, surgicl indication, technique and results of meniscus repair.. Authors comparatively studied 100 cases of meniscus injury in 88 patients (arthroscopic total menisectomy: 16 cases, arthroscopic partial menisectomy: 68 cases, arthroscopic meniscus suturing: 16 cases) from February 1985 to March 1992. The results were as follows: 1. Male (61.4%) was much more affected than female. 2. The third decade group was most commonly affected and the most common causes was sports injury (43.2%) 3. The lateral meniscus was more injured (71%), than the medial (29%) 4. In arthroscopic finding, longitudinal tear (37%) was the most common. 5. According to the Tapper and Hoover's criteria, satisfactory result was 56.3% in arthroscopic meniscus repair group.
