Cells of stratum corneum are sometimes without keratin and living. Examples of non-keratinized stratified squamous epithelium include some parts of the lining of oral cavity , pharynx , conjunctiva of eye , upper one-third esophagus , rectum , vulva , and vagina .
These scars are hypercellular with fibroblasts, myofibroblasts, and some immune cells present. [3] The immature scars can be distinguished from desmoplasia by immunohistochemical staining of biopsied tumors that will reveal the type and organization of cells present as well as whether recent trauma has occurred to the tissue.

Simple squamous epithelium falls under the physiological category of exchange epithelium due to its ability to rapidly transport molecules across the tissue layer. To facilitate this movement, some types of simple squamous epithelium may have pores between cells to allow molecules to move through it, creating a leaky epithelium.
Squamous cells tend to have horizontally flattened, nearly oval-shaped nuclei because of the thin, flattened form of the cell. Squamous epithelium is found lining surfaces such as skin or alveoli in the lung, enabling simple passive diffusion as also found in the alveolar epithelium in the lungs. Specialized squamous epithelium also forms the ...
Differentiating cells delaminate from the basement membrane and are displaced outward through the epidermal layers, undergoing multiple stages of differentiation until, in the stratum corneum, losing their nucleus and fusing to squamous sheets, which are eventually shed from the surface (desquamation).
Tissue mass is defined at 3.3 kg (ICRP-89, ICRP110) and addresses the skin's epidermis, dermis, hair follicles, and glands. The cell data is extracted from 'The Human Cell Count and Cell Size Distribution', [17] [18] Tissue-Table tab in the Supporting Information SO1 Dataset (xlsx). The 1200 record Dataset is supported by extensive references ...
Of nonmelanoma skin cancers, about 80% are basal-cell cancers and 20% squamous-cell skin cancers. [14] Basal-cell and squamous-cell skin cancers rarely result in death. [6] In the United States, they were the cause of less than 0.1% of all cancer deaths. [1] Globally in 2012, melanoma occurred in 232,000 people and resulted in 55,000 deaths. [6]
