(A) Pre-dye spray colonoscopy failed to detect this lesion. This picture was taken after washing out indigo carmine. (B) The dye spraying method with indigo carmine was able to visualise the lesion clearly. Magnifying colonoscopy revealed that the lesion had a type IV pit or neoplastic pattern (inset). (C) A lesion with low grade dysplasia highlighted by the contrast method using indigo carmine. (D) The same lesion as shown in (C) was stained with crystal violet. Glandular openings or pits were more clearly seen.
