Quantitative Assessment of Lymphocytes and Plasma Cells in Leukoplakia, Candidiasis, and Lichen Planus

Abstract

Mononuclear cell infiltration in biopsy specimens of leukoplakia, candidiasis, and lichen planus was assessed quantitatively. Differential counts of pyroninophilic and non-pyroninophilic round cells were related to the histological grades of leukoplakia and to other white lesions. An attempt was made to correlate these indexes to the incidence of carcinomatous transformation.
