Sarcomatoid cholangiocarcinoma with osteoclast-like giant cells: A case report
-
摘要:
<正>胆管癌是起源于胆管上皮细胞具有高度侵袭性的胆道恶性肿瘤,其发病率和死亡率在全球范围内呈上升趋势。目前具有特殊的组织学表现的胆管肿瘤并不多见,其中上皮细胞肿瘤的肉瘤样变化可见于肝脏、胆囊、胰腺和壶腹部[1]。肉瘤样胆管癌是由上皮细胞和间质细胞组成的罕见肿瘤,大多数肉瘤样胆管癌具有肉瘤组分,表现为梭形细胞或多形性细胞分化。而伴有破骨细胞样巨细胞的胆管肉瘤样癌是一种非常罕见的恶性肿瘤,国内外文献少有报道,现就笔者所在医院诊断的1例伴破骨细胞样巨细胞的胆管肉瘤样癌,结合文献对其临床特点、病理学特征、诊治和预后进行初步探讨。
