The Virtual Dermatoscope is a fun and interactive way to improve your dermoscopy skills. Examine each lesion with the Virtual Dermatoscope and attempt the two quizzes to reach a diagnosis.

The original Virtual Dermatoscope was designed as a resource within Cardiff University's Introduction to Dermoscopy course. This is a comprehensive 12-week online course, run by leading international experts in the field.
