We present the case of a 71 year old female that was endoscopically diagnosed with type III neuroendocrine gastric tumor (NET). NETs are rare, slowly growing neoplasm originating in the neuroendocrine cells, that can occur anywhere in the body. Gastrointestinal forms account for more than a half of them. If type I and II gastric neuroendocrine tumors can be managed endoscopically, type III and IV have sugery as their main therapy. Because type III lessions have the greatest potential to generate metastasis, we did a CT scan on the patient and found distant metastasis located in the liver and also to the lymph nodes. Treatment options depend on the type of tumor, its location, signs and symptoms experienced by the patient, due to excess hormones produced by the tumor, and also if there is resectable metastatic disease or not. Altough our patient had a voluminous tumor, surgical resection was possible, followed by chemotherapy, with good evolution.
