Background: Pelvic washing and peritoneal fluid cytology specimens are used to detect peritoneal spread of malignancies. In most cases, identification of malignancy in these specimens is straightforward, but benign processes may occasionally mimic neoplasia and cause diagnostic difficulty. Summary: In this article, we perform a focused review of common benign entities encountered in pelvic washing and peritoneal fluid specimens during routine practice which may cause difficulty and discuss helpful features for avoiding diagnostic pitfalls. Key Messages: Application of strict cytomorphologic criteria, along with judicious use of ancillary studies and correlation with clinical, intraoperative, radiologic, and other pathologic findings, can help resolve most problematic cases.

良性腹腔积液和盆腔清洗标本的细胞学：诊断性细胞形态学特征和缺陷

背景：盆腔清洗液和腹膜液细胞学标本用于检测恶性肿瘤的腹膜扩散。在大多数情况下，在这些标本中识别恶性肿瘤很简单，但良性过程偶尔可能会模仿肿瘤并导致诊断困难。总结：在这篇文章中，我们重点回顾了在常规实践中盆腔冲洗液和腹膜液标本中遇到的常见良性实体，这些实体可能会造成困难，并讨论了避免诊断陷阱的有用特征。关键信息：应用严格的细胞形态学标准，明智地使用辅助研究以及与临床、术中、放射学和其他病理学发现的相关性，可以帮助解决大多数有问题的病例。
