简介:[ 摘要 ] 报告 1 例水光针注射术后继发带状疱疹。患者女, 38 岁,水光针注射术后 11 天,左侧额面部红斑、水疱伴疼痛 5 天。通过对本例的分析总结,对我们今后临床工作中水光针注射术后不良反应的防治有一定意义。

简介:【摘要】目的:结合2019版WHO消化系统肿瘤分类对阑尾杯状细胞腺癌的研究,分析1例以右侧盆腔包块为首发症状的阑尾杯状细胞腺癌的临床特点,病理特征和免疫表型。方法:回顾性分析1例阑尾杯状细胞腺癌伴右侧卵巢转移的临床特点,组织学特征,免疫表型分析及复习相关文献进行讨论。结果:女性,年龄48岁,行右侧卵巢切除,术中冰冻结果(右侧附件)间质内见大量印戒样细胞浸润,低分化癌浸润或转移不能除外。与临床沟通建议检查胃肠道及阑尾。追加阑尾切除,术中冰冻结果(阑尾)见印戒样细胞浸润,杯状细胞腺癌可能,切缘阴性。术后常规病理显示典型的杯状细胞腺癌成分。免疫组化:CK7,CK20,SYN,CgA,CD56均阳。结论:阑尾的杯状细胞腺癌是一种少见肿瘤,大部分没有明确的肿块,术前检查难以发现阑尾病变。以盆腔包块为首发症状,冰冻中见大量印戒细胞时,要考虑到阑尾的杯状细胞腺癌可能,找到原发病灶,为临床进行正确的手术方式提供依据。
