2 Value of Colposcopy Cytology is an effective screening method, and colposcopy with directed biopsy is the critical diagnostic step for women with cervical cytologic abnormalities Decrease diagnostic conization and hysterectomy. Limitation; It takes some time and experience to properly analyze what you see.

3 Role of colposcopist 1. Colposcopist must be able to locate the disease. 2. Colposcopically assess the severity of lesions. 3. Determine the most severe lesion to biopsy. 4. Correlate the colposcopic impression with the cytologic and histologic findings. 5. Then the colposcopist determines the appropriate management or treatment.

4 Practical knowledge Precisely localise TZ, Recognize normal and abnormal TZ, TZ with gland opening, sq.met aplasia, columnar epithelium Clinical skills Punch biopsy, LLETZ

5 Colposcopy: Work-up Explain to the patient. Inspect the vagina and cervix and apply 3-5% acetic acid. Position the colposcope and focus on the cervix with the desired magnification (7X-15X). Drawings the lesion topography and lesion grade(s) Biopsy samples should be obtained from all abnormal lesions. A cytobrush or ECC may be used to evaluate the endocervical pathology. Hemostatic agent can be applied to each biopsy site. Results should be reviewed to confirm.

6 Diagnostic accuracy of colposcopy Calculated based on the agreement of the colposcopic impression with the histologic interpretation within one histologic grade. Limitations; Colposcopy is highly sensitive in well-trained hands, but has low specificity, and, thus, is not a good screening tool.

7 Colposcopical scoring system Colposcopy is a subjective diagnostic method with high sensitivity and low specificity. Because of low specificity, the scoring system for colposcopic findings is important when deciding on the necessity of cervical biopsy, and it contributes to the decreasing of unnecessary biopsy.

8 Colposcopic accuracy The colposcopic accuracy index threshold of 80% appears to be a reasonable proficiency level and a useful goal for training programs. The colposcopist may overestimate minor benign cervical epithelial and vascular alterations that mimic low-grade premalignant disease features. The error is common when the colposcopist has knowledge of a preexisting minor cytologic smear abnormality.

9 Colpo. Appearance of Benign Lesions Keratosis, Erosions and Ulcers, Cervicitis, Atrophy, Nabothian cysts, Ectopy, Deciduosis, Endometriosis, Endocervical polyps. The difficulty lies in learning to distinguish lowgrade lesions from immature metaplasia which also exhibits aceto-whitening and fine vascular patterns. Due to the variability of the colposcopic appearance of low-grade lesions, the accuracy and reproducibility of diagnosis is less than that of higher grade lesions.

10 Colpo. Appearance of Benign Lesions nabothian cyst cervical polyp

11 Colpo. Appearance of Benign Lesions immature squamous metaplasia(pinkish white hue) crypt opening

12 Colpo. Appearance of Benign Lesions immature squamous metaplasia mild acetowhite lesion with fine mosaic and irregular margin

13 Colpo. Appearance of LSIL Flat with a smooth surface, except condylomas. Leukoplakia ; benign hyperkeratosis or low-grade HPV lesions. Variable aceto-whitening; faint Irregular, feathered or geographic outer borders. Partial iodine uptake Either featureless or have fine mosaicism or punctation.

14 Colpo. appearance of Low Grade Lesion mildly dense acetowhite lesion irregular geographical margin

15 Colpo. appearance of HPV infection Condylomas may arise within TZ or as skip lesions within the mature squamous epithelium. The papillary spike-like projections of acuminate warts and the regular projections(asperites) on surface of flat condylomas with colposcopic magnification. It also may be a bright aceto-white, which is characteristic of condyloma.

16 Colpo. appearance of HPV infection The bright aceto-white and the asperites on the surface

17 Colpo. appearance of HSIL Sharply demarcated lesion edges lesion within a lesion or border within a border More prompt and persistent aceto-white change Absence of vessels due to increased lesion density Coarse vascular patterns (punctation, mosaicism, or both), Umbilicated mosaic patterns suggests CIN 3 / carcinoma-in-situ.

18 Colpo. appearance of HSIL dense acetowhite lesion with sharp demarcated margins internal borders within lesion

19 Colpo. appearance of HSIL dense acetowhite lesion with rolled out margins coarse punctation and mosaic with umbilication

20 HSIL site and Topography The most severe disease is found at the most proximal (cephalad) extent of lesion. Size of lesions variable but tends to correlate with severity of disease and risk of occult invasion Size of lesion correlates with risk of treatment failure

21 Colpo. Findings of Adenocarcinoma in Situ The colposcopic findings are often subtle and nonspecific. The two primary findings are (1) a wide area of eversion and (2) ginger root like vessels. Approximately 40% of adenocarcinoma in situ (ACIS) will have an associated SIL. ASCCP guidelines for AGC require colposcopic evaluation and directed biopsies, ECC and D&C for women over 35 years of age.

22 Colpo. Findings of Adenocarcinoma in Situ Pap; ASC-H, HPV(HC); - Biopsy: AIS endocervix CIS exocervix Pap ; HSIL, HPV; 18+ Biopsy; adenocarcinoma, eversion and root like vessels.

23 Colpo. appearance of Invasive cancer The surface is irregular but the borders tend to be sharply defined. In some cases, subtle ulceration can be the only feature present. exophytic mass ulcerative lesion; 12-3 oclock

24 Vaginal colposcopy Indicated when cytology suggests disease in: 1) patients with a normal cervix 2) in patients in whom the cervix is absent The entire surface area of the vagina is examined, including that behind the blades of the speculum. In post hysterectomy patients, the lateral invagination of the vaginal vault must be carefully evaluated. Areas of VaIN are typically discrete with slightly elevated borders and are pinkish or white in color.

25 Colpo. appearance of VaIN Pap; HSIL post-tah state, Pap; mod.dysplasia

26 Colposcopy in pregnant women Cervix must be handled atraumatically in order to avoid bleeding of the congested, hyperaemic tissues. The degree of acetowhitening and the confusing angioarchitecture, with coarse punctation and mosaicism, may give the impression that the lesion is severer than it is.

27 Colposcopy During Pregnancy Increased vascularity produces a cyanotic, bluish hue. progressive eversion of the scj onto the ectocervix makes colposcopy satisfactory more often.
