Welcome back to icliniq.com.
Thanks for adding more pictures. I did review them, but I did not mean to ask for more pictures with better clarity.
It looks more like a flat macule, features more consistent with mole. Please understand that it is extremely difficult to distinguish between early wart and mole just with pictures no matter how clear they are. I strongly feel dermoscopy examination is necessary to make sure that it is not a wart at an early stage. Dermoscope has polarised light, that enhances the features of skin lesions making diagnosis accurate which seems necessary in your case.
Benign mole has very negligible growth and is harmless. Whereas wart grows considerably faster. If you do spot another such lesion or if you see this lesion becoming large/rough then it is absolutely necessary for you to visit a dermatologist in person and get appropriate treatment. Take care.
