(a) The cervix prior to the application of acetic acid; (b) the cervix 30 seconds after acetic acid was applied. (c) The DSI color-coded map, overlaid on the cervix. The upper part of the DSI color scale (red, yellow, and white) indicates persistent/intense acetowhitening. The 11-12 o'clock area highlighted by the map was biopsied and invasive squamous carcinoma was found.

During colposcopy, the transformation zone of the cervix, including the outer limits, was entirely visualized (Figure 1(a)) and acetic acid (3%) was applied. Minimal acetowhitening reaction was observed around the external os (Figure 1(b)). Subsequently, the DSI color-coded map was revealed and reviewed (Figure 1(c)). It highlighted a small acetowhite area around 11-12 o'clock, with colors representing strong/persistent acetowhitening on the color scale of the map (included in Figure 1(c)).
