I can understand your concern. You may have some corn or wart like lesion.  You should go for excision biopsy and histopathological examination.  Then take further treatment if needed. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
