Abstract
背景与目的硬化性肺泡细胞瘤(pulmonary sclerosing pneumocytom, PSP)是临床上相对少见的良性肺肿瘤,多发于中年女性,无典型的临床表现及影像学表现。PSP包括表面立方上皮细胞和圆形间质细胞2种基本细胞类型,有4种组织学类型(出血性、硬化性、实性和乳头状),可发生远处转移,但生长缓慢,术前病理检查易误诊。本研究通过探讨该病的临床特征,旨在提高临床医师对PSP的认识。方法回顾性分析我院2011年1月-2019年12月收治的35例经病理学检查确诊的PSP临床病例资料。结果本研究共35例患者,男性12例,女性23例,平均年龄51岁。7例因体检或常规行胸部计算机断层扫描(computed tomography, CT)偶然发现,28例因咳嗽、咳痰、咯血、胸痛等症状就诊。影像学主要表现为肺部孤立的、边界清楚的圆形或类圆形结节、肿块影。本组有12例行经皮肺穿刺组织病理活检术,仅有7例诊断为PSP。本组共28例行手术治疗,24例术中行快速冷冻病理切片检查,仅5例提示PSP。术后病理检查结果1例诊断肺角化型鳞癌伴局部PSP,其余均诊断为PSP。本组手术和非手术患者出院后随访1年-8年,总体恢复好,复查胸部CT无复发和转移。结论PSP为临床上少见的肺部良性肿瘤,多发于中年女性,临床表现、影像学检查均缺乏特异性,经皮肺穿刺病理检查及术中快速冰冻病理切片容易误诊,多数病例最终需术后病理检查才能明确诊断。
