RESUMEN
Gastric carcinoid tumor is a rare neoplasm and it accounts for only 0.3% of all the gastric neoplasms. Gastric carcinoid tumor has high incidence in patients who are aged between 50 and 70 years, and it usually develops over a long period of time. Type I gastric carcinoid tumors are associated with autoimmune atrophic gastritis and pernicious anemia, and there are a few cases of gastric carcinoids in patients with other autoimmune diseases like Sjogren's syndrome and autoimmune thyroiditis. Here, we report on a case of recurrent type I gastric carcinoid tumors in a 42-years old woman who suffered with systemic lupus erythematosus.

Gastric carcinoid tumor is a neoplasm that arises from enterochromaffine-like (ECL) cells in the gastric fundus. It is a rare disease that comprises less than 2% of all gastric neoplasms; however its incidence has been recently increasing. We experienced one case of gastric carcinoid tumor that was revealed to be multiple polypoid lesions. A 29-year-old female patient visited a hospital three years ago due to syncope. The blood hemoglobin was measured as 6.0 g/dl. Gastroscopy revealed multiple polypoid lesions with bleeding; therefore endoscopic clipping was performed. The polyps were diagnosed as carcinoid tumor via endoscopic biopsy. She was transferred to our hospital because of persistent iron deficiency anemia that was caused by bleeding at the gastric polyps. Gastroscopy revealed more than twenty various-sized polypoid lesions from the mid-body to the antrum. The blood hemoglobin level was 9.0g/dl. Total gastrectomy was performed under the diagnosis of gastric carcinoid tumor with bleeding. All of the gastric polyps were diagnosed as carcinoid tumors, and any metastasis to the regional lymph nodes was not found. Eighteen months after operation, the blood hemoglobin was increased to 12.8g/dl with no evidence of recurrence. Surgical resection should be considered for treating gastric carcinoid tumor with continuous bleeding.

Gastric carcinoid tumors have been regarded as rare neoplasms, accounting for just 0.3% of all gastric tumors and fewer than 2% of all carcinoid tumors. Recently, there has been an increase in the number of reported studies of gastric carcinoid tumors with the widespread use of gastroscopy and improvements in immunohistochemical methods. Gastric carcinoid tumors are classified into three types. For type III gastric carcinoids not associated with hypergastrinemia, which tend to be larger and demonstrate a biologically more aggressive behavior with metastasis, and also for sporadic lesions, excision with regional lymph node clearance has been recommended. Tumors that are less than 1cm in size are called minute carcinoids, which seldom give rise to regional lymph node metastasis, except in rare cases. We report here a rare case of a minute gastric carcinoid tumor with regional lymph node metastasis that was misdiagnosed as an intraabdominal mass in a 42-year-old woman. Furthermore, we review the available literature on this entity.

Gastric carcinoid tumor is a rare neoplasm that occupies less than 1% of total gastric tumor. Especially, gastric carcinoid tumor with hemorrhage has been very rare. A sixty-three-year old male patient was admitted to the hospital because of hematemesis and melena. On the endoscopic examination, a 2 cm-long polypoid mass with central ulcer and hemorrhagic erosions was seen on the anterior wall of the mid-body without active bleeding. Endoscopic ultrasonography revealed that the lesion was limited to submucosa without evidence of metastasis to adjacent lymph node. We experienced a case of gastric carcinoid tumor accompanied with upper gastrointestinal bleeding. The patient underwent extended wedge resection and omentectomy under the diagnosis of type 3 carcinoid tumor. This tentative diagnosis was based on clinical and pathological findings. We report a case of gastric carcinoid with bleeding that is probably type 3.

Objective To investigate the endoscopic feat ures and endoscopical treatment of gastric carcinoid tumors.Methods The clinical and endoscopic materials of 18 patients w ith gastric carcinoid tumors was retrospectively reviewed.Results Five of the 18 patients were benign and 13 were maligna nt. Benign gastric carcinoid tumors were found by biopsy at endoscopy ,and were resected by endoscopic mucosal resection(EMR).Their endoscopic appearance was mu ltiple polypoid masses. 13 malignant patients were confirmed by surgery. Their e ndoscopic appearance was ulcerating and infiltrating lesions.Conclusion Gastroscopy remains to be valuable to set correct di agnosis of gastric carcinoid tumors. EMR may be the first choice for benign gast ric carcinoid tumors.
RESUMEN
Gastric carcinoid tumors were previously believed to be rare lesions, representing less than 2% of all carcinoid tumors and less than 1% of all stomach neoplasms. More recent studies have demonstrated that they may constitute as much as l0-30% of carcinoid tumors. We recently experienced a 35-years old businessman with gastric carcinoid tumor who camplained of postprandial epigastric discomfort. Gastrofiberscope showed protruding mass with central depression and erasion which was located on greater curvature of lower body and its size was 1 x 1 cm. Gastroendoscopic biopsy was per formed. It was identified to carcinoid tumor(Argyrophilic tumor). EUS(endoscopic ultrasonography) revealed that the lesion was limited to submucosa without evidence of any metastasis to adjacent lymph node. The carcinoid tumor was successfully removed by endoscopic polypectomy. Gastrofiberscope and EUS 9months after polypectomy showed that the lesion was nearly normal mucosa without submucosal thickening.
