4、院诊治的 2 例成涎细胞瘤患者，回顾性分析其临床特点、组织学表现、免疫组化特征等，并随访预后。结果2 例均为儿童，确诊年龄分别为 3 岁和 2 月。患儿因发现颌面部肿物进行性增大入院，彩超示腮腺内低回声。术后随访 15 63 个月，生存状态良好，尚无复发或转移。组织学表现:肿瘤组织被纤维结缔组织分隔呈结节状，肿瘤细胞排列成片巢状、腺管样，周围基底样细胞呈栅栏状排列，上皮岛中央可见坏死。例 1 部分区域可见乳头状结构，局部伴出血;例 2 可见较多大小不一的血管结构。肿瘤细胞排列紧密，细胞质少，核圆形卵圆形或多角形，异型性明显。例 1 可见 1 2 个明显核仁，核分裂相易见;例 2 核仁不明显，核
5、分裂相可见。2 例均未见明显血管及神经侵犯。免疫表型:导管上皮表达 CK 和 CK7;Calponin 部分肌上皮呈阳性;SOX-10 和 S-100 肌上皮表达;神经内分泌标志物 CD56、SYN 为阴性;Ki-67 指数分别约 60%、20%。此外，例 1 加做 P63 可见外围肌上皮阳性、AFP 阴性;例 2加做平滑肌肌动蛋白呈阳性。结论成涎细胞瘤罕见，好发于婴幼儿，具有一定侵袭性和复发潜能。该病缺乏典型临床及影像学特点，掌握其病理学特征有助于准确做出诊断。关键词 成涎细胞瘤;唾液腺肿瘤;病理诊断;免疫组织化学DOI:10 3969/j issn 1673-5412 2022 06 01
