A 13-year endoscopic surveillance revealed a growing gastric lesion in a Helicobacter pylori-positive patient. The lesion was identified as benign gastric squamous metaplasia, not malignancy.
Area of Science:
- Gastroenterology
- Endoscopic Imaging
- Pathology
Background:
- A 61-year-old female with Helicobacter pylori infection and gastroesophageal reflux disease underwent annual surveillance endoscopy.
- A 10-mm depressed lesion was noted in the gastric cardia in 2009.
Observation:
- The lesion gradually increased to 15 mm over 13 years.
- Image-enhanced endoscopy techniques (chromoendoscopy, NBI, TCI modes 1 & 2) highlighted the lesion's mucosal characteristics.
- No vascular or structural abnormalities were detected by advanced imaging.
Findings:
- Pathological examination confirmed gastric squamous metaplasia without atypia or malignancy.
- The lesion demonstrated a significant size change over a decade of observation.
Implications:
- This case highlights the importance of long-term endoscopic surveillance for gastric lesions.
- Advanced endoscopic imaging can aid in characterizing benign mucosal changes over time.
- Accurate differentiation of benign lesions from early malignancy is crucial in managing gastric conditions.
