RESUMEN
Multiple carcinoid tumors in stomach are very rare tumors and associated with pernicious anemia, chronic atrophic gastritis and Zollinger-Ellison syndrome. These are believed to be due to hypergastrinemia, resulting in chronic stimulation of enterochromaffine-like (ECL) cells, leading to hyperplasia, metaplasia and ultimately neoplasia. The carcinoid tumor is potentially malignant, even though it may grow slowly, so the treatment of choice must be endoscopic lumpectomy or surgical gastrectomy. The prognosis depends on the site of the tumor and its size. Most carcinoid tumors are less than 1 cm in size and metastasis is uncommon but metastasis in tumors with size over 2 cm is common. A case of multiple carcinoid tumors in stomach, which was successfully removed by endoscopy, is herein reported.

Multiple primary malignant cancer is a disease of more than two cancers occuring in an individual independently. The incidence of multiple primary malignant cancer is increasing gradually due to accurate cancer statistics, early diagnosis and treatment. Multiple primary malignant cancer may be divided into two groups, synchronous or metachronous depending on the interval between their diagnoses. Synchronous cancer is diagnosed simultaneously or within an interval of 6 months and metachronous cancer at interval of more than 6 months. Here, we report a case of synchronous primary triple cancers including stomach, esophagus and liver. The patient was a 63-year-old man with dysphagia. We performed endoscopy, chest and abdominal CT. We found cancers in stomach, esophagus and liver and confirmed triple primary cancer through endoscopic biopsy and sono-guided liver biopsy.
