Epithelial Dysplasia in Actinic Cheilitis: Microscopic Study of 70 Cases from Brazil.

ABSTRACT: To compare two grading systems of epithelial dysplasia-World Health Organization (WHO) and binary system (BS) -in actinic cheilitis (AC). Seventy cases diagnosed as AC in an Oral Pathology Laboratory from Brazil in the last 12 years were retrospectively retrieved, including the demographic data of each patient. All conventionally stained slides were reviewed, and epithelial dysplasia was evaluated by two independent observers using both WHO and BS grading systems. Data correlation was performed using kappa and chi-square tests (p < 0.05). Most patients were white men with a mean age of 57 years old and history of chronic exposure to sunlight.
