[Oral candidiasis in leukoplakia and carcinoma of the oral cavity (author's transl)].
The incidence of Candida albicans and other candida species were examined by mycological culture and histologically in 193 patients with various forms of oral leukoplakia and 14 patients with carcinoma of the oral mucosa, the results being compared with a control group of 137 subjects with a normal mucosa. Comparing the leukoplakia groups one with the other and with the control group revealed definite, usually statistically significant, differences in the incidence of fungi: 46.4% of patients, 29.2% among controls. The incidence of oral fungi was 35.4% among those with noxigenic leukoplakia, 50% in precancerous leukoplakia, 71.5% in mucosal carcinoma, and 49% in nosogenic leukoplakia (mainly lichen planus mucosae). The fungal elements could be demonstrated histologically much less frequently than by culture, but the difference of demonstration was statistically more significant between the different forms of leukoplakia. It is probable that chronic candidiasis in leukoplakia is not carcinogenic as such but is the microbiological and indicator of a local or systemic disorder of the cellular immune system.
