title: Comparative cytologic and histologic studies in oral leukoplakia.
abstract: Comparative analysis of cytologic and histologic results and clinical types of 201 oral leukoplakias has shown: 1) an agreement between cytologic and histologic results in 76.6% of all cases; 2) an occurrence of carcinoma in 32.9% of the erosive leukoplakias in 3.2% of the verrucous leukoplakias, and none in the leukoplakia simplex group; 3) a higher efficacy of cytology in detecting malignancy in the erosive leukoplakia group.
