Ceratoses actínicas (CA) são áreas focais de proliferação e diferenciação anormais de queratinócitos induzidas por exposição crônica à radiação ultravioleta. São muito comuns em área exposta ao sol de indivíduos de pele clara que tiveram exposição excessiva à luz solar. Inicialmente pápulas escamosas planas, podem se tornar significativamente elevadas em relação à superfície da pele pela produção de queratina aderente densa ou como resultado de proliferação celular desregulada que pode progredir para franco carcinoma in situ ou carcinoma espinocelular invasivo. | |||||||||||||||
