A polyp found in the transverse colon
WHAT IS YOUR ENDOSCOPIC DIAGNOSIS?
a) Tubular adenoma
You are half correct!
b) Tubulovillous adenoma
On the left side, the crypt's are slit-like rather than gyrate
c) Villous adenoma
VA's are soft like sea anenome !
d) Serrated polyp
No, the crypts are not large, round openings!
e) Malignant polyp
Yes, there are no crypts on the right-hand side !
explanation
Did you spot that cancer has developed on the right side of this tubular adenoma (TA). On the left side, the crypts are slit-like whilst on the right hand side, the crypt pattern has been destroyed (Kudo type V crypt pattern). The Haggitt stage was I and I took particular care in removing the polyp with a large margin. The cancer was only 4mm in diameter. Perhaps the smallest adenocarcinoma of the colon you will ever see ?
