Introduction:
Endoscopic resection of a follicular lymphoma (FL) presenting as a gastric subepithelial tumor (SET), along with periodic follow up can be a treatment option because gastrointestinal FL cells tend to reside in the primary site, which may explain its indolent nature.
Patient Concerns:
A gastric lesion was found incidentally during a screening endoscopy in 73-year-old woman without any gastrointestinal symptom.
Diagnosis:
The patient was diagnosed with a grade I FL that was 1.4 cm large, at the greater curvature of lower-body.
Intervention:
We performed underwater endoscopic mucosal resection (UW-EMR), and there was no serious complication, such as bleeding and perforation.
Outcomes:
Complete en bloc resection was achieved with UW-EMR. Follow-up endoscopic biopsy after 3 months revealed no residual tumor on the resection site.
Conclusion:
UW-EMR may be a simple and safe resection method for gastric FL without metastases, that measure >1 cm.
