Familial polyposis is a rare hereditary disease characterized by the appearance, early in life, of large numbers of tubular adenoma in the colon and rectum, which is transmitted as a Mendelian dominant, non-sex linked trait. This desease has a tendency to develop malignant change of polyps if not treated. Most of unterated patients die by the age of 45. Early recognition and management of this disease is warranted. We experienced two cases of familial polyposis on 47 and 13 year old male patients and report with review of literatures.

Pseudomyxoma peritonei is a rare diase in which peritoneal surface and omentum are diffusely involvId with gelatiinous mucinous implants and gelatinous ascites. This is commonly associated with the mucoceles of the appendix, ovarian cysts, or mucin secreting carcinomas of the gastrointestinal tract. The mucocele of the appendix is also a rare disease of which the incidence varied from 0.1 to 0.3% in every case of the appendectomy, and would appear to develope as a result of the onstruction in either appendix or large intestine.It seems that pseudomysoma peritonei is caused by the obstruction resulting from the mucin producing adenocarcinoma. the case of pseumomyxoma peritonel orginated from mucinous cystadenocarcinoma of the appendix is reported with a brief review of literature.

Anaplastic thryoid carcinomas are very aggressive and lethal solid tumors; they sometimes show microscopic vascular invasions, but they rarely result in tumor thrombus in the internal jugular vein or in the other great veins of the neck. We encountered a 64-year-old woman with anaplastic thyroid carcinoma and a tumor thrombus that extended from the Lt. internal jugular vein to the innominate vein. Palliative total thyroidectomy, modified radical neck dissection and segmental resection of the Lt. internal jugular vein were done, along with removal of the intravascular tumor thrombus. We recommended postoperative radiotherapy and chemotherapy, but the patient refused additional treatments. We report here on this case for which we first experienced anaplastic thryoid carcinoma associated with tumor thrombus of the internal jugular vein. (Korean J Endocrine Surg 2006;6:102-105)

N/A This is a retrospective study of 25 adults with intussusception, admitted to the branches of CUMC from 1985 to 1991. Intussusception was occured over 35 years of age in the 72% and and the sex incidence was (male: female) 1.8:l. In the symptom duration, 52% of paticnts wore below 7 days and the remained 48% were over 7 days. The clinical symptoms and signs were intermittent abdominal pain (96%), nausea and vomiting (60%), tenderness (48%), diarrhea (28%), abdominal mase (20%), fever (16%), weight loss(16%), abdominal distension (12%) and bloody stool (4%). Ileocolic type. including ileocecal type, was most common (52%) and the ileoileal type was followed (28%). The colocolic type was 12% and the jejunojejunal type was 8%. The prediaposing factors were found in 88% and idiopathic type was 12%. Among them, benign neoplasm was 28%, malignant neoplasm was 40%, and other causes were Meckel's diverticulum, inflammation, and postoperative adhesion. Resection was performed in the 96%. Postoperative complications were wound infection, pneumonia, and acute renal failure. Postoperative death was 1 case and it's cause was acute renal failure. This results indicate that the intussusception in adults has leading cause in 88% and benign and malignant neoplasm are the main CAUSC. In older age, the percentage of malignancy is increased. So early surgical intervention is recommended.

Purpose: The most important prognostic factors in gastric cancer are depth of invasion and lymph node metastasis. Therefore, the prognosis for serosa and lymph node negative gastric cancer is favorable. However, there is no general agreement on the prognostic factors in this subset of patients. This study was undertaken to evaluate the prognostic significances of venous invasion (VI), lymphatic invasion (LI), and perineural invasion (NI) in T1 and T2 gastric cancer without lymph node involvement. Materials and Methods: We retrospectively evaluated 206 patients with T1 and T2, lymph node negative gastric cancer who underwent a curative resection from 1989 to 1993 at Kangnam St. Mary's Hospital, Seoul, Korea. The Chi-square test was used to determine the statistical significance of differences, and the Kaplan-Meier method was used to calculate survival rates. Significant differences in the survival rates were assessed using the log-rank test, and the Cox regression method was used to evaluate independent prognostic significance. Results: The rate of VI, LI and NI correlated well with the depth of tumor invasion. The rates of VI (+) for T1 vs T2 was $0\%\;vs\;5.1\%$, of LI (+) was $5.6\%\;vs\;26.8\%$, and of NI (+) was $1.6\%\;vs\;26.8\%$ in NI (+). There were 13 recurrent cases, 10 cases out of the 13 were T2 gastric cancers, and the recurrence rate was higher in LI (+) and NI (+) cases than in LI (-) and NI (-) cases. The 5-year survival rates were $93.4\%$ in LI (-) cases, $77.4\%$ in LI (+) cases, $92.5\%$ in NI (-) cases, $74\%$ in NI(+) cases, $95.9\%$ in LI (-) NI (-) cases, and $73.9\%$ in LI (+) NI (+) cases. Multivariate analysis demonstrated that simultaneous LI and NI was the only significant factor influencing the prognosis. Conclusion: These results suggest that simultaneous lymphatic and perineural invasion may be an independent prognostic factor in patients with T1 and T2 gastric cancer without lymph node metastasis.
