This chapter reviews non-neoplastic lesions that can be identified in peritoneal washings and ovarian specimens, focusing on how benign entities—especially endometriosis and endosalpingiosis—can mimic low-grade malignancy and create diagnostic uncertainty. It summarizes diagnostic cytopathology approaches, including differential diagnoses and specific cytologic pitfalls encountered in pelvic washings. A key limitation is that the text is a chapter overview rather than an original study, so it does not provide new experimental results or quantified performance metrics. Relevance to endometriosis: the chapter explicitly highlights endometriosis as a common benign finding in peritoneal washings that poses a diagnostic challenge when distinguishing it from low-grade malignancy, though the paper’s main focus is broader non-neoplastic cytology in peritoneal washings and ovary.

Abstract

Peritoneal washing is usually performed to rule out neoplasia or malignancy. Often benign findings such as endometriosis and endosalpingiosis pose a diagnostic challenge to differentiate from a low-grade malignancy. This chapter describes the nonneoplastic lesions seen in peritoneal washings and ovary, along with the differential diagnosis.
