Abstract

A 71-year-old woman was found to have submucosal tumor-like lesion on colonoscopy (CS) before gastric surgery, and computed tomography (CT) showed a 12-mm structure at the base of the appendix. The lesion could not be clearly detected on CT nine months later, but it had enlarged again on CT one year later; therefore, CS and endoscopic ultrasound (EUS) were performed. The lesion was determined to be cystic with viscous contents, and laparoscopic appendicectomy was performed. This is the first report of low-grade appendiceal mucinous neoplasm (LAMN) diagnosed by a histopathologic examination of a resected specimen showing shrinkage and re-expansion of the appendix.

摘要

一名71岁女性在胃部手术前接受结肠镜检查（CS）时发现有黏膜下肿瘤样病变，计算机断层扫描（CT）显示阑尾根部有一个12毫米的结构。9个月后CT上无法清晰检测到该病变，但1年后CT显示其再次增大；因此，进行了结肠镜检查和内镜超声检查（EUS）。病变被确定为含有粘性内容物的囊性病变，并进行了腹腔镜阑尾切除术。这是首例通过对显示阑尾萎缩和再扩张的切除标本进行组织病理学检查诊断出的低级别阑尾黏液性肿瘤（LAMN）报告。
