Type 1 Gastric Neuroendocrine Tumor Found on Endoscopic Polypectomy

Area of Science:

• Gastroenterology
• Oncology
• Pathology

Background:

• Gastric neuroendocrine tumors (GNET) are rare neoplasms, comprising less than 1% of all gastric tumors.
• The World Health Organization (WHO) classification system (types 1-3) aids in predicting GNET malignant potential and guiding management.
• Endoscopic resections show improved outcomes, yet optimal approaches require further investigation.

Observation:

• A 56-year-old woman presented with classic features of a type one GNET.
• The tumor involved the gastric mucosa and submucosa.
• The patient had a history of primary atrophic gastritis, secondary hypergastrinemia, and pernicious anemia.

Findings:

• The case illustrates a type one GNET in the context of specific underlying conditions.
• The variable presentation of GNET complicates treatment standardization.
• Endoscopic resection is a potential treatment, but further research is needed.

Implications:

• This case underscores the importance of recognizing the association between GNET and conditions like atrophic gastritis and pernicious anemia.
• Standardizing diagnostic and therapeutic strategies for GNET remains a challenge due to presentation variability.
• Further research into endoscopic resection techniques is crucial for optimizing GNET management and patient outcomes.
