The distribution of amyloid P component in normal human cervix.

The distribution of amyloid P component in normal human adult cervix was studied using fluorescent immunohistochemical techniques on frozen sections. Amyloid P component is associated with elastic fibres which are particularly concentrated in a sub-epithelial plexus in the ectocervix. This plexus does not extend into the endocervix but terminates at, or just caudal to, the squamocolumnar junction. Amyloid P component was not demonstrated in any of the epithelial basement membranes.
