Standardized Smartphone Photography for Severity Assessment in Pyoderma Gangrenosum: A Pilot Validation Study
Morgan Vague, Martha Oberg, Laura Morales-Leon, Angelo V Marzano, William W Huang, Arash Mostaghimi, Robert I Kelly, Alex G Ortega-LoayzaStandardized photographic methods for pyoderma gangrenosum (PG) severity staging remain poorly defined despite the central role of image-based assessment in monitoring disease course. In this pilot paired validation study, smartphone images obtained under standardized conditions yielded PG severity ratings comparable to DSLR images across 4 expert dermatologists, supporting simple image-capture protocols as a practical framework for reproducible PG photography.
