Inhalation of fungal spores or localized colonization of the skin may initiate persistent infections; therefore, mycoses often start in the lungs or on the skin. In this paper, we present an algorithm to guide the assessment of pigmented lesions of the oral cavity on the basis of history, clinical examination and laboratory investigations (Fig. D) Ingestion of aflatoxin produced by Aspergillus flavus can cause adenocarcinoma of the colon.
