Dermatology is pattern recognition with a grammar. Every case, lab, and game here runs the same four moves until they run themselves.

An atlas you can examine

Real clinical photographs under the dermatoscope, each condition connected to its morphology, its mimics, and its cases, and a blind mode that turns browsing into self-testing.
