[|Human|] I have a bluish spot in my cheek.  Previous to finding the spot, I had noticed a place on my gum (on the same side as the spot, but behind a back tooth) which the oral surgeon told me may be a fibroid.  Soon after that, the "fibroma" went away, but I still have the bluish spot on my cheek.  He is planning a biopsy shortly on this spot.  Does this sound like the correct thing to do, and what do you believe the spot could be?please cancel this asI wasnot told it would cost anything.
[|AI|]  Hello, for your problem, all the medical and dental examinations including laboratory tests such as blood test should be done. There are many lesions which can be present in oral cavity. If the doctor feels to get the biopsy done, then let him/her go ahead. Many such focal pigmentation could be present like vascular malformations, post inflammatory pigmentation, pigmented nevus, etc. so it's better to rule out by various tests. Thank you for your query take care
