摘要 目的总结膀胱原发性淋巴上皮瘤样癌(LELC)的临床病理特征。方法对1例膀胱原发性LELC患者的临床资料进行回顾性分析。结果患者无明显诱因出现间断全程肉眼血尿5个月,尿常规检查提示潜血阳性。尿脱落细胞检查提示可疑肿瘤细胞存在,CT检查示膀胱前壁不规则增厚。术中见膀胱黏膜表面一个3.0 cm×2.5 cm×1.5 cm不规则结节状凸起,镜下可见肿瘤组织呈条索状、巢状或片状聚集,肿瘤细胞呈合体样外观,胞质淡染或略嗜酸性;肿瘤细胞间为淋巴样间质,淋巴细胞与肿瘤细胞密切接触。肿瘤细胞中细胞角蛋白(CK)及CK7阳性、CK20阴性,上皮膜抗原(EMA)、p21、p53、ki-67阳性,CD20、CD3、CD138阳性。病理诊断为膀胱原发性LELC。行膀胱肿瘤切除术,术后予吉西他滨+奥沙利铂全身静脉化疗,术后随访22个月,未发生肿瘤复发、转移。结论膀胱原发性LELC以血尿为主要表现;该病确诊依靠病理检查,镜下可见肿瘤细胞呈合体样外观,胞质淡染或略嗜酸性,肿瘤细胞间为淋巴样间质;肿瘤细胞中CK及CK7表达阳性、CK20阴性,EMA、p21、p53、ki-67阳性,CD20、CD3、CD138阳性。
