【摘要】 目的 探讨阑尾类癌的生物学特性、诊断、误诊原因及外科治疗经验。 方法 回顾性总结自1994～2004年我院收治的12例阑尾类癌术前误诊为阑尾炎患者的临床和病理资料。 结果 本组12例患者术前均误诊为阑尾炎。肿瘤直径小于1cm有8例，1～2cm2例，大于2cm2例。9例肿瘤浸润深度限于黏膜下或黏膜下层，2例侵及浆膜。1例患者肿瘤大于2cm伴局部淋巴结转移。除1例侵及浆膜患者术中行右半结肠切除术，另1例肿瘤直径大于2cm且伴阑尾系膜淋巴结阳性者再次行右半结肠切除术外，其余10例均仅行阑尾切除术。获随访的10例患者中，1例2年后肿瘤复发，二次手术行右半结肠切除术，其余患者均无复发和远处转移。 结论 阑尾类癌少见且多无症状，极易误诊为急性或慢性阑尾炎。小于1cm的阑尾类癌仅做单纯性阑尾切除术即可。肿瘤>2cm的患者应行右半结肠切除术。
