Type 3: Endocervical component, not fully visible. Cervix in relation to upper part of vagina and posterior portion of uterus. Squamous metaplasia of the cervix, with typical features. Pap stain.
The cervical transformation zone and lesion are excised to an adequate depth, which in most cases is at least 8 mm, and extending 4 to 5 mm beyond the lesion. A second pass with a more narrow loop can also be done to obtain an endocervical specimen for further histologic evaluation.
Endocervical curettage is a medical procedure used to extract cells of the endocervix to visualize under a microscope. Direct cervical visualization, colposcopy, and even endocervical colposcopy are not enough to fully analyze all areas of the endocervical epithelium and thus endocervical curettage is the method of choice in cases where this is necessary.
The cervical canal is generally lined by "endocervical mucosa" which consists of a single layer of mucinous columnar epithelium. However, after menopause, the functional squamocolumnar junction moves into the cervical canal, and hence the distal part of the cervical canal may be lined by stratified squamous epithelium (conforming to a "type 3 transformation zone").
