Visually meaningful
The image rewards close observation rather than shock value.
About Dermdle
A sharper eye, one case at a time.
Dermdle is a daily visual diagnosis challenge designed primarily for dermatology residents, with clinicians and medical students as a broader educational audience.
The idea
Dermatology is richly visual. Dermdle begins where a Kodachrome session begins: with the image, a quiet moment of pattern recognition, and a commitment to one diagnosis. When more context is needed, the case unfolds in deliberate stages.
What makes a good Dermdle case
Progressively teachable
Each clue reflects real clinical reasoning and meaningfully narrows the differential.
Reviewed and sourced
Medical content, accepted answers, permissions, and references pass a publication gate.
Respectful by design
Cases use non-stigmatizing language and a balanced range of skin tones and conditions.
Editorial standards
Clinical images, teaching vignettes, answer dictionaries, references, permissions, and review records are managed through a protected editorial workflow. Published cases retain clear source attribution and are presented for education—not patient diagnosis.
