A histopathologic study including iramunohistochemical stains was made in 30 patients who were presented with gastrointestinal lymphoma. The occurrence was 13 in the stomach, 8 in the ileocecum, 7 in the small intestine and 2 in the colon. The disease more frequently affected males than females and the average ages were 53 years in the patients of gastric lymphoma and 44 years in the patients of intestinal lymphoma. Gastric lymphomas were usually presented with a single lesion, and the antrum and/or body were the most common sites. But intestinal lymphomas were presented with a single or multiple lesion, and the ileocecum was the most common site. The most common gross type of gastrointestinal lymphomas was the ulceroinfiltrating type and most are of the diffuse large noncleaved cell type of B-cell lymphoma, histologically. There were 2 cases of T-cell lymphoma presented in the intestine as the superficially ulcerative gross pattern and diffuse immunoblastic cell type. The distinct MALToma was seen in only one case of stomach but the feature was partially remained in each two cases of stomach and intestine. Their coexistent findings may suggest that diffuse large of immunoblastic component arises through blastic transformation of the low-grade M ALToma component.

BACKGROUND: Angiogenesis plays a critical role in human tumor growth and metastasis. Microvessel count, as a measure of tumor angiogenesis, has been significantly correlated with invasive and metastatic patterns in breast, prostate and cutaneous carcinomas. Materials and METHODS: Fifty patients with curatively resected non-small cell lung cancer were evaluated. Tumor tissues embedded in paraffin block were stained by anti CD 31 (PECAM, platelet endothelial cellular adhesion molecule) using immunohistochemical method to assess microvessel count. Microvessels were counted in the most active areas of neovascularization(microscopy, 200×). RESULTS: 1) Mean microvessel count was 47.1 ± 17.7(per 200×field) in total 50 cases. 2) Mean microvessel count of adenocarcinoma (54.4±19.9) was significantly higher than that of squamous cancer(43.9±16.2)(p<0.05), but there were no relationship between microvessel count and TNM stages. 3) Median survival time, 2-year and 5-year survival rates of the low microvascular group(microvessel count<45, 22cases) were 61 months, 80% and 40%, respectively, and those of the high microvascular group(microvessel count ≥ 45, 28 cases) were 46 months, 75% and 12%, respectively. As results, prognosis of low microvascular group is statistically significantly superior to that of the high microvascular group(p=0.0162, Kaplan-Meier, log-rank). CONCLUSION: Angiogenesis assessed by microvessel count can be used as one of the significant prognostic factors in non-small cell lung cancer.

BACKGROUND: Angiogenesis is an essential component of tumor growth and metastasis, and the vascular endothelial growth factor (VEGF) is one of the most important angiogenic factors. Several solid tumors produce substantial amounts of VEGF, which stimulates proliferation and the migration of ednothelial cells, therby inducing neovasculization by a paracrine mechanism. To evaluate the prognostic roles of angiogenesis and VEGF expression in patients with non-small cell lung cancer, the relationship between VEGF expression in tumor tissues, the clinicopathologic features and the overall survival rate were analysed. METHODS: Sixty-nine resected primary non-small cell lung cancer specimens were evaluated. The pareffinembedded tumor tissues were stained by anti-VEGF polyclonal antibodies using an immunohistochemical method to assess VEGF expression. RESULTS: In Forty-one patients (59%), the VEGF antigen was expressed weakly in their tumor tissue, whereas in twenty-eight patients (41%) the VEGF antigen was expressed strongly. The median survival time of the weak VEGF expression group was 24 months, and that of the strong VEGF expression group was 19 months. The three year-survival rates were 35%, 33%, respectively. The survival difference between both groups was not statistically significnat. CONCLUSION: Although results were not statistically significant, the strong expression group tended to poorer prognosis than weak expression group.

Tuberculosis is a common chronic infectious disease, although the spleen is an uncommon organ to harbor tubercle bacilli. Immunocompromised subjects are primarily prone to miliary tuberculosis and in them the spleen is invaded by Mycobacterium tuberculosis. Spleen tuberculosis is manifested commonly as a miliary form. The basic pathology is granulomatous inflammation. The CT finding of splenic tuberculosis are multiple, well-defined, roung or ovoid, low-density masses. Lymphadenopathy in the abdomen and mediastinum and pleural effusion can be found. We report two cases with tuberculosis of the spleen proved by computed tomography and histologic identification. One paitient did not improve following antituberculous medication, so splenectomy was performed. The other patient has been treated with antituberculous medication.

"Idiopathic long QT syndrome" is characterized by prolongation of the QT interval due to unusual electrocardiographic repolarization abnormality and associated with variable clinical manifestations from no specific symptoms in lifetime to syncope or even sudden death. The prognosis of this syndrome is very grave and motality is approximately 50% within 10 years among untreated symptomatic patients after the initial syncope. But this sudden onset syncope may be misdiagnosed as epilepsy, being treated with antiepileptic drug for many years. However, this high mortality has been significantly reduced to less than 5% by the effective therapy. Therefore, it is crucial to make an early and accurate dianosis. We exprienced a case of 34 months old male who presented with recurrent syncopal attacks. He had no specific neurological abnomal finding except congenital deafness. He had normal EEG and brain MRI findings but ECG showed prolonged QT interval (QTc= 0.5), findings of which were compatible with long QT syndrome. He is currently being followed at OPD, but the pateint is still experiencing syncopal attack despite of treatment with beta-blocker, atenolol. Therefore, we are considering an insertion of pacemaker or performing thoracic sympathectomy.

BACKGROUND/AIMS: Intestinal lymphangiectasia is a disease characterized by dilated lymphatics of the intestinal mucosa and excessive enteric loss of plasma proteins. Instead of multiple blind peroral jejunal biopsy, duodenal endoscopy and endoscopic small bowel biopsy were performed. We evaluated the significance of endoscopic small bowel biopsy and the usefulness of the other diagnostic methods in the diagnosis of intestinal lymphangiectasia in children. METHODS: Fourteen children seen between August 1989 and August 1997 with clinically suggestive intestinal lymphangiectasia were analysed. The median age at onset of symptoms was 4 years. Primary intestinal lymphangiectasia occurred in 10 children and secondary intestinal lymphangiectasia occurred in 4 children, of whom two had Fontan operation, one had constrictive pericarditis, and one had Crohn's disease. Low fat, high protein diet with medium chain triglycerides was the mainstay of treatment. RESULTS: 1) Diarrhea was present in 14 patients, and edema in 11 patients. Hypocalcemic tetany occurred in 6 children and vomiting in 5 children. Dight children had ascites and three of these had chylous ascites. Growth retardation was present in four patients, chylothorax in one, and lymphedema in one. The initial serum albumin concentration was 1.8 g/dl, the serum calcium level 6.7 mg/dl, and the total lymphocyte count 623 /mm(3). 2) Dilated lymphatics in the small bowel mucosa was confirmed by endoscopic biopsy in 14 children(100%). The sensitivity of alpha1-antitrypsin clearance was 100%. Duodenal endoscopy showed scattered white spots covering mucosa in 11 children(79%). Small bowel series revealed thickened mucosal folds in 10 children(77%). Four(31%) had positive finding of 99mTc-antimony lymphoscintigraphy. 3) Responses to treatment in children with primary intestinal lymphangiectasia were graded as good if the symptoms resolved, and poor if there was no lasting resolution of symptoms and repeated albumin administration. Response to therapy was good in four and poor in six patients. The mean age at onset of symptoms was 8 years in good resonse group, and 2 years in poor response group (p<0.05). CONCLUSION: The diagnosis of intestinal lymphangiectasia is confirmed by duodenoscopy and endoscopic small bowel biopsy in a child with diarrhea, edema, hypoalbuminemia, and lymphocytopenia. As compared with other diagnostic methods such as small bowel series and lymphoscintigraphy, duodenoscopy and endoscopic small bowel biopsy are very sensitive and should be performed early.

The incidence of colorectal cancer has been increased gradually and it was about 6.9% of all malignancies in Korea. Early diagnosis was recognized as the most important factor influencing the prognosis of colorectal cancer and the incidence of early colorectal cancer was increasing. Thus great change was observed in the treatment of early colorectal cancer, endoscopic therapy as well as curative surgical resection is being accepted. We report a case of effective and safe endoscopic therapy for early rectal cancer in 5S-year-old male patient. He presented with rectal prolapse and bleeding of a year's duration. A large polypoid mass with fine nodular surface and thick, short stalk was seen in the rectum at 4cm above the anal verge during flexible sigmoidoscopy. After the histologic examination of specimen obtained by bite biopsy, CT scan of pelvic cavity and ultrasonogram of abdomen, the tumor was removed safe and completely by 2 sessions of piecemeal polypectomies and strip biopsy. He has been well without symptoms and signs of recurrence of rectal cancer for 20 months.
