Q

Highlighters used in case of Colposcopic Biopsy to see abnormal areas and Findings

A

1) Acetic acid - Rapidly dividing areas will become white ij color (Acetowhite areas) - take sample
2) Schillers or Lugol iodine - Stains glycogen rich areas - become Mahogany’s brown color - sample is taken from unstained areas

26
Q

CIN 3 management if Biopsy finding shows some cells already invading into stroma of cervix

A

Invasive cancer cervix
Treatment - Radical Hysterectomy

27
Q

CIN 3 Management if Biopsy finding shows abnormal cells only in surface, no invasion

A

Biopsy Proven CIN 3
Management -1) Excision of transformation using a large loop AKA Loop electrosurgical excision procedure (LEEP)
2) Laser ablation - requires too much training, expensive
3) Cryocautery
