HHS Vulnerability Disclosure, Help MIB1 immunohistochemical stain showed a Ki-67 proliferation index of less than 3% within these aggregates, which was pathologically suggestive of a type 1 microneuroendocrine tumor (Figure 2). Jensen RT, Cadiot G, Brandi ML, et al. This leads to the absence of gastric acid production causing compensatory hyperplasia of gastric antral G-cells with hypergastrinemia.10 Furthermore, there is potentially decreased inhibition from gastric D-cells, contributing to increased gastrin production. ScientificWorldJournal. The classifications of neuroendocrine proliferations that lead from enterochromaffin-like cell hyperplasia to neuroendocrine tumors in the stomach are complicated and relatively inaccessible to nonspecialists. Therefore, a negative or positive reaction with a single marker cannot be recommended in routine practice to establish or exclude the diagnosis of an endocrine tumor. Endocr Pathol. Given the oncogenic potential of ECL cells changes, a regular endoscopic and histological follow-up of the patient is advisable when ECL cells hyperplastic and dysplastic proliferations are detected in gastric biopsy specimens.
