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) |
