Kudo pit pattern
The Kudo pit pattern can be assessed on endoscopy and predicts the presence or absence of neoplasia and malignancy.
Tabular summary
It is as follows:[1]
| Type | Pit morphology | Significance |
|---|---|---|
| I | round | non-neoplastic |
| II | stellate or papillary | non-neoplastic |
| III | tubular | neoplastic (adenomatous) |
| IV | branch-like | neoplastic (adenomatous) |
| V | irregular/non-structural | neoplastic (invasive) |
Pattern V is usually subdivided:
| Type | Pit morphology | Significance |
|---|---|---|
| VI | irregular | invasive cancer |
| VN | non-structural areas | invasive cancer |
