Strange polyps !

These peculiar colonic lesions were found in the colon of an asymptomatic patient.
WHAT ARE THEY? 

■ Inflammatory polyps

Absolutely!

■ Adenomatous polyps

These are too long and peculiar looking to be adenomatous!

■ Hamartomatous polyps

No way!

explanation

These peculiar things are post-inflammatory polyps found in a patient with quiescent colitis. They are an endoscopic diagnosis and taking a sample will only reveal 'normal colonic mucosa'.  In patients with more 'recent' inflammation, the polyps appear more red as in the example below!
