This image was taken 3 days post experimental inoculation with highly pathogenic avian influenza. An incision has been made over the swollen hock joint, revealing a subcutaneous accumulation of serohemorrhagic exudate, consistent with edema.
Pathologic description: 
The skin overlying the swollen joint has been peeled back to reveal the subcutaneous tissue and portions of the joint capsule. The tissue is slightly wet, and the blood vessels are prominent. Near the left side of the photo, there is a short linear incision into the joint capsule and the tendon attachment. This incision reveals the accumulation of a small amount of yellow tinged fluid in the tissue.
