A 76-year-old Japanese woman visited a nearby clinic complaining of a dull feeling in the stomach.
Esophagogastroduodenoscopy (EGD) revealed a depressed lesion at a gastric angle of the greater curvature side.
The clinical diagnosis of early gastric cancer was considered by EGD findings.
No specific finding was obtained by laboratory testing.
The narrow band imaging of EGD showed a relatively demarcated lesion with an irregular microsurface pattern.
Pathological findings of endoscopic submucosal dissection (ESD) specimens indicated the diagnosis of gastric adenocarcinoma of fundic gland type (GA-FG) with a signet-ring cell carcinoma component.
Only ESD was performed for treatment.
To the best of our knowledge, no GA-FG case with a poorly differentiated adenocarcinoma or signet-ring cell carcinoma component has been reported.
The term GA-FG describes gastric adenocarcinoma of fundic gland type.
This is the first case report of GA-FG with a signet-ring cell carcinoma component.
