###Human: Why does my tonsil look like a white build up with veins on it? ###Assistant: Hi. The left tonsil seems mildly hypertrophied and unhealthy. But it does not have any active infection. Can you take a picture with both tonsils in view? Tonsils are normal structures and unless one is much bigger than the other we usually do not suspect anything. Do you have any symptoms with tonsils? Is there a post nasal drip or throat pain or soreness or foreign body sensation in the throat?  The tonsils inside the nose or at the back of nose are called nasopharyngeal tonsils or the adenoids which usually regress by 10 years of age but in some, they remain. How old are you? What appliances are you wearing or using for jaw bone correction? Can you take a picture and send?  The tonsillar biopsy is not as simple as biopsies at other locations. We do it under general anesthesia and we remove the entire tonsil. This is done at a particular position and probably your jaw condition does not let that position to be made on you. Do revert back with all the details so that we can help you.
