Here are five polyps in five patients.
CAN YOU TELL WHICH IMAGE IS SHOWING;
■ TA + LGD
Polyp A shows a small TA with LGD (most small polyps are TA's)
■ TA + HGD
Polyp E is a TA with HGD. All LST-NG's are TA's and many harbour HGD or even superficial invasive cancer. Recognise them and try to remove them single fragment or in as few fragments as possible.
■ TVA + LGD
Polyp D is a LST-G type of polyp. LST-G's are almost always TVA's with no more than LGD. When they 'turn' they usually develop a nodule at the site of cancer.
■ TVA + HGD
Polyp B is a sessile TVA with HGD. Of course the Devil has Horns! Furthermore, in large sessile polyps surface biopsies may not reveal what hides deeper inside ...
■ NON-NEOPLASTIC
Polyp C is an ugly little polyp without any crypts composed entirely of inflamed granulation tissue.
