ERCPMP-Gx: Endoscopic Image and Video Dataset for Morphological, Histopathological, and Genomic Characterization of Colorectal Polyposis

TL;DR - ERCPMP-Gx is a public, patient-level dataset linking colorectal polyposis endoscopy images and videos with histopathology and germline findings. It addresses a gap in multimodal data for AI-assisted recognition and classification of hereditary polyposis syndromes.

• Contains 160 images plus video clips captured with white-light and multiple narrow-band imaging modes.
• Approximately 80% of cases involve clinically or genetically confirmed hereditary syndromes; 20% are non-hereditary polyps or mimicking lesions for differential classification.
• Covers familial adenomatous, Peutz-Jeghers, juvenile, and ganglioneuroma polyposis syndromes.
• Records include standardized endoscopic annotations and, where available, representative histopathology and clinically reported germline findings.
