This lesion could indicate a local bacteria infection, possibly ringworm, an insect bite, or just an area of rotation of unknown cause. You could continue to monitor if you feel comfortable and if it does not go away within a few days I would reconsider seeing your veterinarian to ensure it's nothing contagious like ringworm. However if it starts to grow, bleed, become raised, or seems painful it should be seen sooner. In the meantime you could consider cleaning it with a very mild soap and warm water and keeping it clean and dry during the day. As there is a possibility it could be ringworm wash your hands thoroughly after handling the site.
