Carcinoid tumor of stomach continue to interest clinician because of the rarity and difficulty in diagnosis clioically with infrequent classical carcinoid syndrome. Recently, we experienced a case of gastric carcinoid with hemetemesis and melena. We feel that this case is an instructive example of the fascinating variety of entities which can result in massive upper gastrointestinal bleeding. So we present this case with s review of relevant literatures.

Polyarteritis nodosa(PAN) is a multisystemic disease primarily involving the small and medium- sized vessels. Prognosis depends on the presence and severity of visceral involvement. Gastrioin- testinal involvement in PQN may result in vague abdominal pain, nausea and melena. Angio- graphy can be used to establish a diagnosis of PAN. We report a case of polyarteritis nodosa presenting with recurrent abdominal pain, melena and vomiting, which was diagnosed by celiac angiography, and treated with prednisloln.

Brunners gland adenoma is a benign epithelial tumor of the duodenum originating from submucosal Brunners gland. This is an extremely rare entity that account for only 10.6% of benign duodenal tumor, which are themselves relatively rare, representing 0.008% of all surgical and autopsy specimens. The clinical manifestation are nonspecific gastrointestinal complaints, such as bloating or epigastric pain, and the tumor gives rise to melena or anemia, due to the ulceration or erosion of the tumor. The diagnosis is usually made by radiologic studies and gastroduodenal endoscopy which can also provide definitive treatment. The aim of treatment is complete removal of the lesion and exclude malignancy. We report on 4 cases of Brunners gland adenoma which was confirmed by operation or endoscopic polypectomy.

Malignant fibrous histiocytoma (MFH) occurs primarily in the extremities and trunk, however primary malignant fibrous histiocytoma of the alimentary tract, particularly of the jejunum, is uncommon. This case report presents a case of malignant fibrous histiocytoma as the primary lesion of the jejunum in a 42-year-old male patient with a 10-day history of melena. A small bowel tumor was resected without complication. The final diagnosis was based on the pathological report of the surgical specimen.

Gastric metastasis occurs in about 0.7% to 1.7%, of patients dying of solid tumors of extragastrointestinal origin. Metastatic disease involving the stomach is an unusual and difficult clinical problem and presenting symptoms include nonspecific epigastric pain and melena. In most cases of gastric metastasis, the histologic finding of the gastroscopic biopsy suggests the correct diagnosis. There are only a few reports of gastric metastasis from malignant melanoma. We report a case of malignat melanoma of gastric metastasis, which was diagnosed by gastroscopy.

Primary aortoenteric fistula is a direct communication between the aorta and intestinal lumen and it represents a rare but potentially lethal complication of an abdominal aortic aneurysm. However, it may occur less frequently in a naive non-aneurysmatic aorta. Diagnosis is often difficult and delayed in most cases, unless there is a high level of clinical awareness. Urgent surgery is still the recommended treatment. We describe the case of primary aortoenteric fistula of a saccular aneurysm. A 55-year-old woman was referred to our center with hematemesis, melena, and severe anemia who was dignosed previously with unknown saccular abdominal aneurysm.

BACKGROUND AND AIMS: The Dieulafoy's lesion is an unusual cause of massive gastrointestinal bleeding resulting from the erosion of an abnormally large submucosal artery. Surgical intervention was believed to be the best treatment in the past, but recently improvement of endoscopic techniques has made effective hemostasis possible in most cases of Dieulafoy's lesions. Therapeutic endoscopic hemostasis includes sclerotherapy, electrocauterization, laser coagulotherapy, clipping band ligation. The effectiveness of the endoscopic band ligation was evaluated in bleeding Dieulafoy's lesions. METHODS: Clinical characteristics, initial endoscopic findings, and effectiveness of band ligation in Dieulafoy's lesions were all analyzed. RESULTS: 1) The patients were 8 males and 1 female, and the mean age was 56.2 years. 2) The chief complaints were melena and hematemesis, and 2 cases had histories of recurrent gastrointestinal bleeding. 3) The diagnosis of Dieulafoy's lesion was possible in 7 of 9 patients (78%) at the initial endoscopy. 4) The lesions were mostly located in the fundus and the body, characterized mainly by protruding vessels in shallow erosion areas. 5) The initial band ligation was possible with successful hemostasis, but additional sclerotherapy was necessary in two cases. There were no complications related to the procedure, except a case of early band detachment. CONCLUSIONS: The Dieulafoy's lesion requires careful endoscopic observation for diagnosis, and endoscopic band ligation was an effective therapeutic option for bleeding Dieulafoy's lesions.

The endoscopic diagnosis of gastric carcinoid has been considered difficult. Reported cases of this tumor diagnosed by endoscopic examination are rare. And the gastric carcinoid with massive upper gastrointestinal bleeding is a rare disease entity. We experienced a case of gastric carcinoid admitted to the hospital because of hematemesis, melena and syncope. And it was diagnosed by endoscopic biopsy, although it resembled type IIa+IIc early gastric cancer at endoscopic examination. To our knowledge, this is the first case report of gastric carcinoid tumor mimicking early gastric cancer. So we report this case with a review of relevant literatures.

Duodenal gastrointestinal stromal tumors (GISTs) are relatively rare tumors that commonly present with gastrointestinal bleeding. Evaluation with endoscopic ultrasonography (EUS) is a useful technique for the differential diagnosis of GISTs from other submucosal tumors. A 58-year-old man presented with melena and anemia. An esophago-gastroduodenoscopy showed the presence of a submucosal tumor in the second portion of the duodenum with central ulceration and a flat spot. EUS showed the presence of a suspicious malignant GIST that originated from the proper muscle layer, which was successfully resected. We report a case of a duodenal GIST with a bleeding ulcer. Positive reactivity for CD117 and S-100 was demonstrated by immunohistochemical staining.
