摘要 胰腺混合性腺泡导管癌是一种罕见的侵袭性胰腺癌,肿瘤中包含胰腺导管及胰腺腺泡分化2种成分。胰腺导管内混合性腺泡导管癌则更为罕见。本文报道1例发生在58岁女性胰腺导管内的混合性腺泡导管癌病例,就诊时以慢性胰腺炎伴导管扩张迁延起病。肿瘤大体沿胰腺导管乳头样生长,伴导管扩张。镜下肿瘤沿导管生长,呈乳头样息肉凸起。可见2种成分,腺泡细胞癌的成分:肿瘤实性生长,细胞具有嗜酸颗粒状胞质及明显核仁;腺癌的成分:肿瘤细胞形成腺管结构,具有细胞内外黏液。免疫组织化学染色示腺泡细胞癌成分bcl-10及糜蛋白酶阳性,导管癌成分阿辛蓝-过碘酸雪夫染色阳性;2种成分广谱细胞角蛋白及β-catenin均膜阳性,而神经内分泌标志物CD56、突触素及嗜铬粒素A均阴性;p53弱到中度阳性,Ki-67阳性指数15%。胰腺导管内的生长方式是胰腺混合性腺泡导管癌一种极为少见的生长方式,患者以非特异性胰腺炎症状慢性迁延起病,临床表现不典型,及时正确的诊断对患者的治疗和预后评估非常重要。
