A 55-year-old Japanese woman, who had been diagnosed with ulcerative colitis at 18 years of age, underwent screening endoscopy examinations. Esophagogastroduodenoscopy revealed an extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of the stomach. Colonoscopy showed a slightly elevated reddish lesion with dilated microvessels but no erosions or ulcers. Although MALT lymphoma in the cecum was endoscopically suspected, flow cytometry and pathological analyses led to the diagnosis of appendiceal orifice inflammation in ulcerative colitis. This case highlights the diversity of the endoscopic appearance of appendiceal orifice inflammation in ulcerative colitis.

一名55岁的日本女性，18岁时被诊断为溃疡性结肠炎，接受了内镜筛查检查。食管胃十二指肠镜检查发现胃黏膜相关淋巴组织结外边缘区淋巴瘤（MALT淋巴瘤）。结肠镜检查显示有一个微红的略微隆起的病变，微血管扩张，但无糜烂或溃疡。尽管在盲肠的MALT淋巴瘤在内镜检查中被怀疑，但流式细胞术和病理分析诊断为溃疡性结肠炎的阑尾开口炎症。该病例突出了溃疡性结肠炎中阑尾开口炎症内镜表现的多样性。
