question: Hello, I have a white patch just inside my mouth. I went to see a doctor and he thinks it is probably a fibroma that is probably benign. But I just read where the fibromas in the mouth are usually pink in color and they are usually firm. Mine is white in color and is not soft and really firm. I also just read that HIV and AIDS are possible diagnoses and that concerned me. I am making an appointment tomorrow to see a dentist, but I am just trying to do some research in the meantime.
