Submandibular region: edema; Wattles: hemorrhages.
Morphologic diagnosis:
Subcutaneous tissue (ventral neck and head): Severe acute diffuse edema. Subcutaneous tissue (wattles): Moderate acute multifocal hemorrhage.
Clinical description:
This image was taken 4 days post experimental inoculation with highly pathogenic avian influenza. There is a severe accumulation of serous exudate in the wattles and intermandibular space. In HPAI, edema tends to be most pronounced in the face and neck regions.
Pathologic description:
The skin on the ventral neck and intramandibular space has been opened to reveal the subcutaneous structures. The subcutaneous tissues are gelatinous and expanded by clear, yellow tinged fluid. The edges of the wattles can be seen on the edges of the reflected skin. These tissues contain numerous, bright red hemorrhages.
