The unique aspect of this case consists of the presence of a previously treated prostatic malignancy, with an apparently good outcome in the absence of lymph nodes and bone metastasis, and the subsequent detection of an advanced metastatic disease. In many cases, tumors remain asymptomatic and may be diagnosed as incidental findings during upper gastrointestinal endoscopy. World J Gastrointest Oncol 2020;12:791807.

This . In conclusion, AMAG is a rare but important condition to consider on the differential diagnosis in patients with dyspepsia, especially in the setting of other autoimmune comorbidities. Gastrointestinal neuroendocrine neoplasms (NENs) represent a heterogeneous group of neoplasms originating from endocrine cells that are located in the gastrointestinal tract. 7.

A possible explanation for this behavior could be the persistence of ectopic gastrin cells in atrophic corporeal mucosa and hypergastrinemia which promotes tumor growth. Eur J Gastroenterol Hepatol.

[Autoimmune metaplastic atrophic gastritis, G cell hyperplasia and neuroendocrine tumor of stomach]. Malignancies of the stomach and esophagus remain devastating for the patient and challenging for the treating physician. The histological diagnosis and tumor grading according to standard terminology is important in estimating tumor behavior and in adopting the best therapeutic decision. These NENs can be preceded by ECL cells hyperplastic and dysplastic lesions, whose oncologic potential has not yet been fully elucidated.
