Pannus

From Wikipedia, the free encyclopedia

Pannus is a medical term for a hanging flap of skin. It is usually found in the abdomen of people who have recently lost a significant amount of weight. Pannus is commonly referred to as "fat folds" or "rolls." These are not complimentary terms. Skin conditions such as yeast infections under the pannus are common problems. Pannus can be corrected by plastic surgery, commonly called a "tummy tuck".

In people suffering from rheumatoid arthritis, pannus tissue eventually forms in the joint affected by the disease, causing loss of bone and cartilage.

In ophthalmology, "'pannus'" refers to the growth of blood vessels into the peripheral cornea. In normal individuals, the cornea is avascular. Chronic local hypoxia (such as that occurring with overuse of contact lenses) or inflammation may lead to peripheral corneal vascularization, or pannus. Pannus may also develop in diseases of the corneal stem cells, such as aniridia.

Similarly, in veterinary medicine pannus means a chronic inflammation in the cornea of dogs.
