Pathobiology Questions
Hello A period!
I wanted to share a few disease-related finds with you and ask for your thoughts...
Upon arrival in Louisiana, we stayed at a bed and breakfast next to the Audubon Park. Below are pictures of two birds with "tumor-like" characteristics. Look them over, do some research, and send me your hypotheses as to their diagnosis. Good Luck!
Bird A
Bird B

Tumors are caused by replicating cells, that do not stop when they are supposed to. One of the causes of these tumors on the birds is the Avian Papilloma Virus. The birds can be tested for the virus by microscopic examination of a sample taken from the area where the tumor is located. Papillomas on birds do not primarily need to be treated, unless the area infected could be potentially debilitating. Both of these birds should be tested for the papilloma virus, because their lesions could be debilitating and harmful.
Hyaluronic acid, which is a polysaccharide that is found in many animal tissues and bacteria capsuls can result in the growth of tumors on fowl. This is called Rous Sarcoma and it could possibly be what these birds have. It was originally a virus that affected chicken, but has adapted itself to duck.Ducks were inoculated with the virus in laboratory studies, they treated ducks with high doses of cortisone and then invected them with the virus. Tumor growth was very rapid, and even though it is primarily found in chickens, they found that it could, in fact affect ducks.
Do the birds have xanthoma? This is a common condition in birds that causes the buildup of fatty lipids under the skin, which form tumorlike bulges.
This could perhaps be a type of Avian caner. These lumps could also be cysts, a lot of the time common on birds. Many feather cysts are often filled with keratin. The tumor may be benign or malignant.

Bird A- unknown, maybe fatty tumor.
Bird B- naural appearance.

The tumor seen on the foot of the duck is most likely benign due to the fact that there are no other visible growths, therefore suggesting that the tumor is not spreading to other body parts. The growths covering the face of the other duck may be malignant because it looks as though it is spreading over the duck’s head and down its neck. More information is needed to determine the cause of the growths on both birds.
Good hypotheses about the birds! The first bird may have a lipoma (fatty tumor) or it may be swelling from a foot injury. Hard to tell without examining it closely. However, the second duck is called a Muscovey Duck and is suppose to have those red bumps all over its head!!! Pretty weird! :)
