cervical squamous metaplasia
Wednesday 28 August 2013
A squamous metaplasia can sometimes be found in the endocervix, as it is composed of simple columnar epithelium, whereas the ectocervix is composed of stratified squamous non-keratinized epithelium.
Squamous Metaplasia represents focal or extensive replacement of the mucus-secreting glandular epithelium by stratified squamous epithelium, the pathogenesis of this process, also known as prosoplasia .
Most commonly, the process involves only the superficial epithelium and is recognized by the presence of squamous epithelium overlying endocervical glands.
In other instances, it affects the glandular component as well.
