SUMMARY The ear‐lobe sign is seen in those who develop contact dermatitis to a substance applied with one hand to the skin of the face and neck. On the ipsilateral side of the face the ear‐lobe is spared whereas on the contralateral side the ear‐lobe is involved. The sign manifests because of the unique combination of the anatomy of the hand and the sweeping movement the hand makes during application.
