The Kudo pit pattern can be assessed on colonoscopy and predicts the presence or absence of neoplasia and malignancy.[1]

Tabular summary

It is as follows:[2]

Pattern Pit morphology Significance
Type I round non-neoplastic
Type II stellate or papillary non-neoplastic
Type III tubular neoplastic (adenomatous)
Type IV branch-like neoplastic (adenomatous)
Type VI irregular neoplastic (invasive)
Type VN non-structural areas neoplastic (invasive)

Notes:

  • A modified version includes a Type II-O pattern that is highly specific for SSAs.[3]
