<s>[INST] Hi doctor, My son, who is 6 years old, has a bump on the palm of his hand. It is a hard bump, and he is on antibiotic Cefalexin 259 mg. Is this a wart? It does not pain on touching. He has had this for about a week and a half. His primary care doctor did not seem to know what it was so she prescribed an antibiotic. I have attached a photo of the bump. [/INST] Hi. I have seen the photo (attachment removed to protect patient identity). For more information consult a dermatologist online --> </s>
