《Slide 15.》Cervical erosion with squamous metaplasia , Uterine cervix

A. Brief Descriptions：

1. Squamous metaplasia is defined by replacement of mucin-secreting columnar epithelium by stratified squamous epithelium.

2. Cause: local ( vaginal ) environmental factors, trauma, chronic irritation, cervical infection.

B. Gross Findings：

1. When viewed with naked eye, the endocervical mucosa appears as a red, velvety zone, sharply contrasting with the neighboring pink, translucent squamous epithelium.

C. Micro Findings：

1. Squamous epithelial cells growth under the columnar endocervical mucosa,  then the columnar cells degenerate and sloughed.

2. Cystic dilation of endocervical glands known as Nabothian cysts.

D. Others:
