In-person clinical diagnoses
Each case is one patient consultation, with one primary diagnosis made in person by the treating dermatologist.
Smartphone and professional-camera images
Real-world smartphone photographs plus professional-camera imagery, to train and evaluate across capture conditions.
Diverse geographies and skin tones
Cases from multiple countries and practices, spanning a range of skin tones.
Custom selections from 1,000 images
Subsets by condition, volume, demographics, or capture type, with complimentary evaluation samples.
Condition-level counts and distributions are shared during scoping.
What's in a case
Images plus structured metadata, documented plainly
Every case links clinical photographs to a single diagnosis and a small, consistent set of fields, so you can split, stratify, and audit your data with confidence.
Images
Real-world captureMain dataset images were taken on smartphones during clinical consultations. Professional-camera imagery is available in additional collections.
Multiple views per caseMost cases include several photographs of the same presentation.

Data quality & de-identification
Reviewed by medical professionals, case by case
Data is collected in clinical practice and goes through manual review before it is offered for licensing.
01 · CAPTURE
In-person consultation
Photographs are taken during the visit, and the treating dermatologist records the diagnosis.
02 · STRUCTURE
One case per patient
Collection is designed around one case per unique patient, with residual duplication estimated below 1%.
03 · REVIEW
Manual medical QC
Each case is checked for duplicates, image quality, age and sex accuracy, and de-identification.
04 · PROTECT
De-identified delivery
Records carry de-identified IDs, not names or contact details, and are licensed only under a signed agreement.
HIPAA-aligned de-identification. Our documented patient de-identification process is aligned with HIPAA Safe Harbor methods. We are happy to walk your compliance team through it during scoping.
