Scattered Tiny Whitish Protrusions in the Stomach Are a Clue to the Diagnosis of Autoimmune Gastritis

JaLCDOI	10.18926/AMO/64365
FullText URL	77_1_75.pdf
Author	Iwamuro, Masaya\| Tanaka, Takehiro\| Hamada, Kenta\| Kono, Yoshiyasu\| Kanzaki, Hiromitsu\| Kawano, Seiji\| Kawahara, Yoshiro\| Okada, Hiroyuki\|
Abstract	Herein, we report two patients with autoimmune gastritis who had undergone multiple esophagogastroduodenoscopy procedures for 17 and 9 years, respectively, before their diagnosis. Instead, they had been diagnosed with and treated for Helicobacter pylori-associated gastritis. The correct diagnosis was made when scatterings of tiny whitish protrusions in the gastric mucosa were detected on esophagogastroduodenoscopy. Our findings suggest that scattered tiny whitish bumps may be a clue to the diagnosis of autoimmune gastritis.
