  • Generally, not a problem pathologists see.
  • May be associated with aortic stenosis; known as Heyde syndrome.[1]

Epidemiology:

  • Older people.

Etiology:

  • Thought to be caused by the higher wall tension of cecum (due to larger diameter) and result from (intermittent) venous occlusion/focal dilation of vessels.[2]

Gros=

  • Cecum - classic location.
