White Lesions of the Oral Cavity or Mouth and their Clinical Features
Hi,
Dentist found isolated white lesions on the upper right side gum.
There is no coloration he said. He has ordered for a biopsy.
The lesions are very small in size, 1 to 2 mm clusters, each of them having about 5 isolated lesions of size of a pin point.
Is it very serious condition?
I am 67 yrs old woman. No bad habits like eating betal, smoking, tobacco chewing etc.
Thanks,
Viji
Without any image, it is difficult to come to a diagnosis of the exact condition or differential diagnosis. From what you have explaining they appear like – Fordyce Granules – http://www.juniordentist.com/fordyce-granules.html. If the lesions on your gums are similar to the ones in the link I have posted they are most likely harmless Fordyce Granules. But in case they are malignant a Biopsy will rule it out.
