The swelling of the structures of the head (comb, wattles, and periocular regions) are one of the most frequent external findings associated with highly pathogenic avian influenza.
Pathologic description:
The subcutaneous tissues of the head are swollen. The eyelids are thickened, causing them not to open all the way. The wattle and comb are bright red and the comb is slightly swollen. The feather loss is due to normal molting.
