Abstract

Objective: A case of intestinal spirochaetosis diagnosed in anal cytology is presented.

Methods: An anal liquid-based cytology was performed and stained with Papanicolau and Warthin-Starry stains.

Results: An apical filamentous "fringe" was identified in columnar cells groups.

Conclusion: Anal cytology is a potential tool for intestinal spirochaetosis diagnosis.
