An adenosquamous carcinoma is a malignancy that has both glandular and squamous histologic components. Both components are malignant and have potential to metastasize. An adenosquamous carcinoma of the large bowel is rare, and its clinicopathologic behavior is not fully understood. It is reported to be more aggressive and have a worse prognosis when it is compared with an adenocarcinoma alone. We present a case of an adenosquamous carcinoma in the ascending colon which was laparoscopically resected and followed by adjuvant chemotherapy.

Hepatic lymphangioma is a rare benign neoplasm. It usually occurs as a part of systemic lymphangiomatosis. Isolated hepatic lymphangioma is extremely rare. A 58-year-old woman with weight loss was referred for the evaluation of chronic renal insufficiency and hepatic mass. Abdominal computed tomography showed 3 cm sized multilobulated cystic lesion with calcification and thick septal enhancing focus in the segment V of the liver. On abdominal magnetic resonance imaging, the masses exhibited low signal intensity on the T1-weighted images and high signal intensity on the T2-weighted images. Malignant tumor could not be ruled out, and therefore, the patient underwent right anterior segmentectomy of the liver. Gross pathology reveraled a 3.0x2.2x1.5 cm mass with multichamber cyst, which was filled with mucoid material. Histologically the mass was composed of irregularly shaped vascular channels filled acellular homogeneous lymph fluids. The final diagnosis was hepatic isolated cavernous lymphangioma. Herein, we report a case of isolated hepatic lymphangioma and also review the existing literature.

In order to evaluate the accuracy of endoscopic findings in the diagnosis of gastric can the endoscopic findings of gastric lesion were compared with the macroscopic and pathologic findings of excised identical lesion. 105 operated gastric cancer paitients (advanced cancer 95 cases, early cancer 10 cases) who were diagnosed endoscopically at Pusan National University Hospital from January 1983 to August 1987 were studied. The results were as follows; 1) The accuracy of endoscopic findings were 94.7% in the advanced gastric cancer, and 45.5% in the early gastric cancer. 2) The accuracy of gross findings endoscopic and pathologic in advanced gastric cancer were 50.0% in Borrmann type I, 45.0% in Borrmann type II, 73.2% in Borrmann type III, and 66.7% in Borrmann tyye IV. 3) The accuracy of the endoscopy ia morphologic classification of advanced gastric cancer according to pathologic tumor location were 60.0% in C (upper 1/3), 43.9% in M(middle 1/3),76.3% in A (lower 1/3), 55.6% in the anterior wall, 50.0% in the posterior wall, 66.7% in the greater curavature, and 67.2% in the lesser curvature. 4) The accuracy of endoacopy in morphologic classification of gastric cancer to tumor size ware 54.5% in below 2 cm, 54.5% in from 2.1 cm to 4 cm, 65.4% in from 4.1 cm to 6.0 cm, 80% in from 6.1 cm to 8 cm, 75.0% in above 8.1 cm. 5) The accuracy of endoscopy in the morphologic classification according to the pathologic tumor stage in advanced gastric cancer were 55.6% in TNM stage I, 52.0% in TNM stage II, 65.4% in TNM stage III, and 73,7% in TNM stage IV.

Primary T-cell lymphoma of the duodenum is uncommon, and peripheral T-cell lymphoma of the duodenum is extremely rare. Approximately 90% of primary gastrointestinal lymphomas originate from B-cells and fewer than 10% originate from T-cells. A peripheral T-cell lymphoma involved in the small intestine is usually detected by complications such as gastrointestinal bleeding, perforation, or obstruction. A 57-year-old man complained of postprandial discomfort and weight loss of 5 kg for 1 month. An esophagogastroduodenoscopy showed a deep ulcer with blood clots and whitish exudates. We conducted a Whipple's operation because of the high risk of ulcer perforation and difficulty in distinguishing the ulcer from malignancy. The resected tissue was confirmed as a peripheral T-cell lymphoma. We reported a case of peripheral T-cell lymphoma of the duodenum and jejunum that extended to the pancreatic head where a diffuse lesion was found without any complications or specific symptoms.

Gastric cancer is the most common malignancy in Korea. The most common cancers of the stomach are adenocarcinomas. Adenosquamous carcinoma of the stomach is very rare, constituting less than 0.1% of all the gastric cancers. Adenosquamous carcinoma is characterized by the presence of two different cell components, one adenomatous and the other squamous. It occurs more frequently in the upper stomach, and it sometimes invades the muscular layer. Adenosquamous carcinoma limited to the mucosa or submucosa is extremely rare and usually invades deeply into the muscular layer. Thus, it is found in an advanced stage at diagnosis and has a worse prognosis than adenocarcinoma. We report a case of early gastric cancer of adenosquamous carcinoma type on the basis of standard endoscopy in a 76-year-old woman. The patient received endoscopic submucosal dissection followed by subtotal gastrectomy to achieve complete resection.

Metachronous double cancer of primary early esophageal squamous cell carcinoma and invasive thymoma is a very rare condition. The invasive thymoma had been detected during the myathenia gravis evaluation and treated by radiation therapy 5 years ago. The esophageal lesion had a nodular-surfaced flat elevation at the mid-esophagus that was found by esophagoscopy. Radical resection for the lesions was undertaken after histologic confirmation. Postoperative pathologic examination documented that the esophageal squamous cell carcinoma was in the "early" stage involving the mucosal and submucosal layer only. We report a case of early esophageal cancer associated with invasive thyrnoma with literatures review.

Peritoneal mesothelioma is a rare disease which arises from the mesothelial lining cells in the peritoneum and spreads to the peritoneal wall, omentum and other abdomina1 organs. Aabestos is one etiologic factor and the other factors are genetic cause, radiation, exposure to toxic materials and recurrent yeritonitis. We experienced a case of multiple small nodular peritoneal mesothelioma after exposure to asbestos for over 20 years. He was a sailor and had worked in the engine department of the ship, in which he wrapped up the pipe of engine in asbestos. This person came to our hospital because of inconvenience due to a distended abdomen. Tumor markers were all within normal limits and there was no evidence of tuberculosis in the abdomen and chest. The CT findings of the abdomen were as follows: There was abundant ascites in the abdominal cavity and multiple small nodules on the parietal peritoneum and especially on the lower abdomen. The omentum thickened diffusely. It was difficult to distinguish from peritoneal mesothelioma and peritoneal carcinomatosis or intestinal tuberculosis. The laparoscopic findings were as follows: There were multiple small nodules on the parietal peritoneum and omentum. The small nodules were a gray white color and uneven compared to tuberculous peritonitis. Therefore, we observed the malignant mesothelial cells by means of the light microscope and electron microscope and concluded that this case was peritoneal mesothelioma.

Extrahepatic metastasis of Hepatocellular carcinoma(HCC) to the gastrointestinal tract is uncommon. Because most of metastases to the gastrointestinal tract have no clinical manifestations, they are usually found incidentally at the time of an autopsy or a laparotomy, We experienced a case of duodenal metastasis of HCC, which presented UGI bleeding. A 59 years old male was admitted to our hospital due to generalized jaundice, which lasted for about a week. From the third day of admission, he had episodes of hematemesis and melena. An abdoinal CT scan demonstrated multiple, variable sized low-density masses in the entire liver with portal vein thrombosis and conglomerated lymph nodes. An esophagogastroduodenoscopy showed a protruded submucosal mass-like lesion with multiple ulceration in the duodenal bulb. We confirmed the duodenal mass-like lesion to be hepatocellular carcinoma by a biopsy and a histoimmunochemical study.

We presented here a rare case of intestinal Behecet's disease simulating Grohn's disease. A 20 year old female complained of recurrence of oral ulcer, genital ulcer, arthralgia, erythema nodosum, abdominal pain and diarrhea, but she had no anal ulcer or anal fistulas. The colonoscopic examanation disclosed diffuse colonie involvement with multiple longitudinal ulcers and inflammatory pseudopolyposis. In hospital, she received ileocecectomy because of distal ilea perforation. Postoperative specimen showed multiple geographic ulcer on ileocecal region, creeping mesenteric fat and thickening of cecal wall. Pathological examination showed perivasculitis, transmural inflammation, fissuring, multiple lymph follicles which are compatible with intestinal Behect's disease. There were no granuloma sugges tive of Crohn's disease. Clinically, the patient met the international criteria of Behcet's disease. Punched out ulcer in the ileocecal region and pathological findings described above confirmed the diagnosis of intestinal Behcet's disease.

The occurrence of the small intestinal adenocarcinoma is infrequent and the primary adenocarcinoma of the jejunum is rare. The survival of adenocarcinoma of the small bowel does not improve over the past three decades. Although symptoms appeared to be of long duration, most patients were diagnosed with advanced disease. All reports agree that these tumors are difficult to achieve good examination of the small bowel by both clinician and radiologist, so it cause a significant delay in diagnosis. The survival of these tumors appear to correlate with stage at presentation, and therefore early and aggressive diagnostic intervention seems to improve the outlook. We report a case of primary jejunal adenocarcinoma assoeiated with iron deficiency anemia with literatures review.
