Therefore, this group of diseases is grouped under the name epidermal differentiation disorders (EDD).1 The epidermis is a tissue with a very well-demarcated structure: the constantly dividing stem cells responsible for regenerating the epithelium (keratinocytes) are located in the stratum basale and the cells generated from this division undergo a gradual process of differentiation as they migrate toward the surface.2 This differentiation process (called cornification) causes morphological changes in keratinocytes due to changes in protein expression patterns, reorganization of the cytoskeleton, lipid secretion, and establishment of intercellular junctions, culminating in the formation of the stratum corneum, which is the most superficial layer of the epidermis, in which keratinocytes have terminally differentiated into corneocytes, cells lacking nuclei and organelles whose cytoplasm is completely filled with structural proteins
