Hello doctor,

I have a rough patch of hardened skin on the back of my feet. It has been a year since I had this. Is it called as callus or corn? Would you please give me your valuable suggestion? Regards.



Welcome to icliniq.com.

Thanks for writing in, and I understand your concern. As per the report provided (attachments removed to protect the patient's identity), it looks like verruca plantaris which means warts that appear on foot. It is a viral infection that usually transmits from person to person through sharing their belongings especially footwear of an infected person. It keeps spreading till appropriate treatment is taken. Callus as mentioned in the history looks slightly different from this. It appears at a different area of the foot and would not be widespread. I will suggest a few things to follow. Undergo radiofrequency electrocautery. The affected area would be burned superficially to remove the infected area. It will heal within a few weeks, and normal skin will be formed. It is done after using a numbing cream and sometimes injectable anesthetic will be used only on the affected area. This is the most effective and faster way of getting rid of them. If you prefer medications over electrocautery, you may start medications then. Use Salactin solution (Salicylic acid and Lactic acid). This has to be applied using a dropper on the affected area alone. The area around the lesion should be protected by applying the vaseline, and this solution should be applied to the lesion alone. Following this, plaster should be used to secure the solution. This has to be done at night. The following day, remove the plaster, soak your foot in lukewarm salt water for 10 minutes and scrub the area lightly using a pumice stone. Be very gentle with the scrub. This is to make it softer. Repeat the application of the solution at night with plaster and soak the following day. Keep doing the same for at least three weeks. Take tablet Ascazin (Zinc Acetate) 50 mg twice daily, once in the morning after food and one at night. Take this for one month. It helps in reducing the transmission and helps in clearing the lesion. If anyone you know has been infected, do make sure they are treated to stop the transmission. I hope this helps. Regards.
