What Is the Scj

The squamocolumnar junction (SCJ) (fig. 5) is defined as the junction between the squamous epithelium and the columnar epithelium. Its location on the cervix is variable. The SCJ is the result of a continuous remodeling process resulting from uterine growth, cervical enlargement and hormonal status.

Is the SCJ the transformation zone?

The transformation zone is located outside of the squamocolumnar junction (SCJ), between the original SCJ (usually not visible on colposcopy) and the current SCJ (Figure 1).

What are Acetowhite changes?

Acetowhite changes may be associated with coats of white paint. The higher CIN grade the more layers of paint. The surface contours of the acetowhite areas associated with high-grade CIN lesions are tending to be irregular and nodular.
