报告2例恶性肿瘤腹腔淋巴结广泛转移发生阑尾穿孔。认为盖尾穿孔快、迅速形成弥漫性腹膜炎的原因可能与回盲部转移淋巴结直接压迫阑尾管壁、大网膜萎缩、机体免疫功能低下、腹腔放射治疗及全身化学治疗有关；指出临床表现与阑尾病理生理变化不一致是导致误诊的主要原因，对治疗措施进行分析。
Two cases of peritoneal lymph node dissection occurred in malignant tumors with appendix perforation. It is concluded that the perforation of the tail caudate and the rapid formation of diffuse peritonitis may be related to the direct compression of the appendix wall, the atrophy of the omentum, the immunocompromised body, the peritoneal radiotherapy and systemic chemotherapy in the lymph node metastasis of the ileocecal region. Inconsistent pathophysiological changes are the main reasons leading to misdiagnosis, and the analysis of treatment measures.
