title: DNA content in reactive hyperplasia, precancerosis, and carcinomas of the oral cavity. A cytophotometric study.
abstract: Cytophotometry has been used to study DNA content in oral epithelial cells of Feulgen-stained specimens from a total of 43 patients: 3 with erythema exudativum multiforme (EEM), 5 with pemphigus, 3 with stomatitis aphtosa, 5 with lichen ruber planus, 8 with leukoplakia, and 19 with carcinomas. In contrast to reactive hyperplasia (EEM, pemphigus, stomatitis aphthosa) leukoplakia has histograms closest to those of carcinoma, with a high percentage of cells in the polyploid regions. This emphasizes the significance of cytophotometry for diagnosis of preneoplastic and neoplastic lesions of the oral cavity.
