Unusual findings in diarrheal disease: Detection of a microscopic entity of unclear significance

Abstract

A 70-year-old woman presented with abdominal pain and diarrhea, with negative stool tests for common pathogens. Microscopy revealed a unique round structure with hyaline pseudopod-like extensions and a double membrane. While literature suggests a potential link to Urbanorum, a debated entity first reported in the 1990s, its classification remains uncertain. This case highlights the importance of rigorous methodologies to establish the clinical significance of such findings.
