Low-grade mucinous neoplasia is an uncommon benign tumor that develops in the appendix. The development of mucocele disease has never been reported in a colonic diverticulum. We present a case developing low-grade mucinous neoplasia in a cecal diverticulum.
A tumor in the ileocecal region was found during a medical examination of a 66-year-old woman. Three months later, the tumor was still present and the patient developed abdominal pain. Laparoscopic ileocecal resection with D2 lymph node dissection was performed. Histopathological examination revealed a low-grade mucinous neoplasm in a cecal diverticulum.
Colonic mucoceles reportedly originate from the appendix. There are no previous reports of mucocele disease in a colonic diverticulum worldwide. This report reviews and discusses the management of the appendiceal mucoceles.
The incidence of colonic diverticula has recently begun to increase in Japan. The possibility of a mucocele within a colonic diverticulum should be considered in patients with submucosal colonic tumors.
低度黏液性肿瘤是一种在阑尾发生的罕见良性肿瘤。结肠憩室中从未有过黏液囊肿病发生的报道。我们报告一例在盲肠憩室发生低度黏液性肿瘤的病例。
一名66岁女性在体检时发现回盲部有一个肿瘤。三个月后，肿瘤仍然存在，患者出现腹痛。进行了腹腔镜下回盲部切除术并清扫D2淋巴结。组织病理学检查显示盲肠憩室中有低度黏液性肿瘤。
据报道，结肠黏液囊肿起源于阑尾。全球范围内此前尚无结肠憩室中黏液囊肿病的报道。本报告回顾并讨论了阑尾黏液囊肿的处理。
在日本，结肠憩室的发病率最近开始上升。对于患有结肠黏膜下肿瘤的患者，应考虑结肠憩室内存在黏液囊肿的可能性。
