Abstract
The structure of and the differentiation gradients for various cytoplasmic constituents in human leukoplakia simplex epithelium were identical at both sites. The differentiation pattern of leukoplakic epithelia was adversely different from that of the respective normal epithelium. This alteration which resulted in a striking resemblance between the leukoplakic epithelia and those of normal skin or hard palatum conceivably can be regarded as a squamous metaplasia characterized by the conversion of one differentiation pattern into another. This shift in the differentiation pattern hardly could have been disclosed by means other than stereologic morphometry.
