Abstract
The corpus intra cristam is a structure observed within the cristae mitochondriales of cells of hyperplastic epidermis. A similar structure has been observed in cells undergoing squamous metaplasia. As it enlarges it seems to destroy the surrounding mitochondrion. Once free in cytoplasm, it may act as a center of agglomeration of tonofilaments and RNP granules to form the so-called "keratohyaline granule". Its contribution to the phenomenon of keratinization is not known.
