Abstract:
A 61-year-old man with Graves disease presented with bilateral perimalleolar cobblestoned plaques, elephantiasic pretibial myxoedema, with a linear koebnerized tract.

This vignette spotlights the dermatology-internal medicine interface: a distinctive cutaneous sign of thyroid autoimmunity with atypical ankle/foot involvement and trauma/friction as a cofactor.
