Section | Pattern |
General assessment | Adequate or inadequate for the reason (eg, cervix obscured by inflammation, bleeding, scar) |
Squamocolumnar junction visibility: completely visible, partially visible, not visible |
Transformation zone types 1, 2, 3 |
Normal colposcopic findings | Original squamous epithelium: mature, atrophic |
Columnar epithelium, ectopy/ectropion |
Metaplastic squamous epithelium, nabothian cysts, crypt (gland) openings |
Deciduosis in pregnancy |
Abnormal colposcopic findings | General principles |
Location of the lesion: inside or outside the transformation zone, location of the lesion by clock position |
Size of the lesion: number of cervical quadrants the lesion covers |
Size of the lesion as percentage of cervix |
Grade 1 (minor): fine mosaic; fine punctation; thin acetowhite epithelium; irregular, geographic border |
Grade 2 (major): sharp border, inner border sign, ridge sign, dense acetowhite epithelium, coarse mosaic, coarse punctation, rapid appearance of acetowhitening, cuffed crypt (gland) openings |
Nonspecific: leukoplakia (keratosis, hyperkeratosis), erosion |
Lugol's staining (Schiller's test): stained or nonstained |
Suspicious for invasion | Atypical vessels |
Additional signs: fragile vessels, irregular surface, exophytic lesion, necrosis, ulceration (necrotic), tumor or gross neoplasm |
Miscellaneous findings | Congenital transformation zone, condyloma, polyp (ectocervical or endocervical), inflammation, stenosis, congenital anomaly, posttreatment consequence, endometriosis |
