What type of ulcer is commonly associated with severe burns?

The type of ulcer commonly associated with severe burns is Curling's ulcer. Curling's ulcer is a specific type of stress ulcer that occurs in patients with significant burns or severe trauma. This phenomenon can be understood through the physiological stress response activated by severe burns. The body’s response to the acute stress from burns includes decreased blood flow to the gastric mucosa, which can lead to ischemia and, subsequently, mucosal injury and ulcer formation.

In the setting of severe burns, there is significant release of stress hormones such as catecholamines and glucocorticoids, which contribute to gastric mucosal damage. Curling's ulcers are typically found in the duodenum, where the damage is most pronounced.

Considering the other options, while duodenal ulcers and stomach ulcers can occur in various circumstances, they are not specifically linked to the context of burn injuries. The term peptic ulcer is a broader category that includes both gastric and duodenal ulcers but does not denote the specific association with severe burns as Curling's ulcer does. Thus, Curling's ulcer is the correct designation for ulcers arising specifically from severe burn injuries.
