MiNENs represent a distinct category, combining neuroendocrine and non-neuroendocrine components. One review article suggests that surveillance every 612 months with endoscopic mucosal resection is sufficient for tumors less than 2 cm vs surgical antrectomy for larger or progressive tumors; however, data are limited on the optimal management of microneuroendocrine tumors.2 Some options to consider include EGD with EUS as was performed for our patient or potentially using virtual chromoendoscopy, an imaging technique that evolving research has shown to be beneficial in identifying and classifying neuroendocrine tumors.12,13.

[6]. In general practice gastric biopsy specimens are often numerically and topographically inadequate for the evaluation of atrophic gastritis; therefore, we have included an algorithm to address specifically the steps that should be taken when confronted with suboptimal sampling. However, in another patient treated by antrectomy, postoperatively gastrin levels remained higher than normal, and NET recurrence was reported 5 years after the antrectomy. 2021 Jun 18;22(12):6548. doi: 10.3390/ijms22126548.
