Cov cim qhia uas yuav tsum ua rau ib tus xav tias qhov kev hloov pauv ntawm actinic keratosis mus rau hauv squamous cell carcinoma yog qhov kis tau sai ntawm keratosis thiab nws cov infiltration (plaque ua ntau o thiab infiltrates ntawm daim tawv nqaij, poob nws tus cwj pwm supple kom nyuaj). Tom qab ntawd, nws tuaj yeem erode los yog txawm tias rwj thiab sprout.
