epithelium

 [ep″ĭ-the´le-um] (pl. epithe´lia) (Gr.)
the cellular covering of internal and external surfaces of the body, including the lining of vessels and other small cavities. It consists of cells joined by small amounts of cementing substances. Epithelium is classified into types on the basis of the number of layers deep and the shape of the superficial cells.
ciliated epithelium epithelium bearing vibratile, hairlike processes (cilia) on its free surface.
columnar epithelium epithelium whose cells are of much greater height than width.
cuboidal epithelium epithelium whose cells are of approximately the same height and width, and appear square in transverse section.
germinal epithelium thickened peritoneal epithelium covering the gonad from earliest development; formerly thought to give rise to germ cells.
glandular epithelium that composed of secreting cells.
pigmentary epithelium (pigmented epithelium) that made of cells containing granules of pigment.
sense epithelium (sensory epithelium) neuroepithelium (def. 1).
simple epithelium that composed of a single layer of cells.
squamous epithelium that composed of flattened platelike cells.
stratified epithelium epithelium made up of cells arranged in layers.
transitional epithelium a type characteristically found lining hollow organs, such as the urinary bladder, that are subject to great mechanical change due to contraction and distention; originally thought to represent a transition between stratified squamous and columnar epithelium.

Five- to eight-cell-layer thick, regular keratinized stratified squamous epithelium without rete ridges lines the cyst.
This leads to the normal acidic pH in the vagina (range, 3.5-4.5) and helps maintain the normal ecosystem of the lower urogenital tract.1 The acidic pH, along with a healthy stratified squamous epithelium, affords protection against various vaginal pathogens.
The classic histopathology findings included the following: (1) a skin tag: stratified squamous epithelium with occasionally striated muscles or cartilage; (2) a main lesion: stratified squamous epithelium with surface parakeratosis and absence of dermal adnexal structures, with mild inflammatory infiltrate of lymphocytes, plasma cells, and neutrophils possibly present; and (3) a sinus tract: squamous or pseudostratified columnar epithelium.
Final histology confirmed the diagnosis of a mature teratoma, with presence of tissues from all three germ layers (e.g., stratified squamous epithelium with adnexal structures (ectoderm), skeletal muscle (mesoderm), and ciliated respiratory epithelium (endoderm)).
