I am writing to seek your advice regarding a skin issue my child has been experiencing. For over a month now, my child has had a kind of fat on her hand (please see the attached photo). While it does not appear to cause pain, it has not gone away, and I am concerned about what it might be. Could you kindly review the attached image and advise us on whether we need to visit the clinic for an examination or if there is any treatment we can begin at home?
