leukoplakia
the fact that the lesion starts and stops is more worrisome than if it were one discontinuous lesion; you would want to take multiple incisional biopsies in this case

lichen planus
take incisional biopsy
what are the four possibilities of a leukoplakia biopsy?
- hyperkeratosis
- dysplasia (mild, moderate, severe)
- carcinoma-in-situ
- squamous cell carcinoma
what are the 3 high risk sites for leukoplakia?
floor of mouth > tongue > lip
what is the best guide to potential progression of oral lesions?
degree of dysplasia
severe dysplasia has ___% transformation rate
moderate dysplasia has ___% transformation rate
mild dysplasia has ___% transformation rate
16%, 3-15%, <5%
a dx of mild dysplasia does not necessarily warrant excisional biopsy; you can watch it and determine treatment from there
in any case, excision significantly reduces the transformation rate
what is the average transformation time for leukoplakia?
4.3 years
