1. Teat-end Callosity consists of a hyperplasia of the Stratum corneum (Neijenhuis et al., 2000b)

2. A circumscribed, conical, horny induration and thickening of the stratum Corneum that causes severe pain by pressure on nerve endings in the corium

3. Crusted scabies: a severe form of scabies with innumerable mites in thickened stratum corneum; has been linked with cellular immune deficiencies, including AIDS

4. Callus shows a markedly dense, usually orthokeratotic stratum corneum underlain by mild acathosis, variable hypergranulosis, and increased collagenization of the superficial dermis

5. Blisters occur where the stratum corneum (the outer cell layer) is very thick, as is the case on the sole of the foot and palm of hands

6. The adaptation to land from amphibians to Amniotes was accompanied by drastic changes of the integument, some of which might be reconstructed by studying the formation of the stratum corneum during embryogenesis

7. In addition to its possible role in capillary adhesion, the epidermal ridge - sweat gland complex of A. pygmaeus has a unique epidermal histo-architecture. Here, the stratum corneum consists of horizontal rows of cell remnants that do not become flattened or adpressed to form a stratified squamous epithelium.
