This document discusses colposcopy findings including: 1. Leukoplakia appears as a thick white patch on the epithelium before acetic acid is applied. 2. Acetowhiteness appears as an opaque white or gray color after applying 3-5% acetic acid and is caused by coagulation of proteins. 3. Punctation appears as red dots over a whitish background and corresponds to preserved central capillaries of columnar villi.
