【摘要】 目的 探讨乳腺分叶状肿瘤的临床特点、治疗方法及其预后因素。方法 回顾性分析我院诊治的26例乳腺分叶状肿瘤患者资料，包括临床症状、体征和辅助检查结果，手术治疗方式及预后。结果 26例患者手术后病理报告分叶状纤维腺瘤(phylloides fibroadenoma)17例，叶状囊肉瘤(cystosarcoma phylloides)9例，其中低度恶性叶状囊肉瘤5例，中度恶性叶状囊肉瘤2例，高度恶性叶状囊肉瘤2例，随访中有5例局部复发，再次手术后随访至今未见复发，全组病例随访至今1例死亡。结论 乳腺分叶状肿瘤发病率低，临床上极易误诊，手术治疗是其首选的治疗方法，包括局部切除和单纯乳房切除术，手术后大多数乳腺分叶状肿瘤预后较好。
