3 months ago I had a biop done on both sides of my tongue. The results came back negative, thank God.The diagnosis was minimal hyperparakeratosis and degenerative vacuolar change of the stratum spinosum. The tissues were white in color....now yesterday I noticied that there's an area on one side that is black and about 5 mm in diameter. I'm going back to my surgeon next week..This black area recently appeared...I'm bumned... a weeks a long time to wait.
