Squamo-columnar junction of cervix

The squamo-columnar junction (SCJ) of the cervix refers to a transitional area between squamous epithelium of the vagina and the columnar epithelium of the endocervix. This shifts in location through age from being more external to internal. Carcinoma of the cervix develops almost exclusively within the transformation zone that extends between the original SCJ and the physiological SCJ 1.
