ACUTE gastroduodenal ulceration occurring in association with major illness,^1,2burns³(Curling's ulcer), or central nervous system trauma^4-6(Cushing's ulcer) is generally referred to as "stress ulceration." Although the exact mechanism of their development is unknown, the lesions are characteristically shallow ulcers or erosions, often multiple, and without surrounding induration or microscopic evidence of chronic inflammatory response.
