The duodenal bulb is the part of the duodenum that lies closest to the stomach and is usually about five centimeters long. It is positioned in front of the liver and the gallbladder, and above the pancreatic head. The portal vein, common bile duct and the gastro-duodenal artery are all behind it, and it begins at the pylorus and finishes at the neck of the gallbladder.

If somebody has a duodenal ulcer, (which are more common than gastric ulcers) this is the place where it would be found.

Erythema, which comes from the Greek word, erythros and which means red, is any redness of the skin that is caused by hyperemia of the capillaries that are situated in the lower layers of the skin. Hyperemia means that there is an unusually high level of blood somewhere in the body.

This can occur with an injury or an infection, but is also the reason behind blushing through nervousness or embarrassment. Other reasons for erythema are acne medication, allergies, massage, hair removal through waxing or tweezing, sunburn, electrical treatment and exercise. It can also be brought about through radiotherapy treatment.

In up to 50 per cent of incidences of erythema, the cause of it cannot be determined. To have it occur in the duodenal bulb, though, means that some causes can definitely be ruled out: Sunburn, exercise and hair removal methods, for example. There should also be consideration given to how anybody would know that they have erythema of the duodenal bulb. The answer to the question of what it is, is that it is a redness, but the assumption has to be made that it is indicated by pain, which leads to the conclusion that there is some sort of infection, injury or ulcer.
