NAPLEX Examination.
Practice Question # 51.
Naplex
Ulcer size.
- The average duodenal ulcer typically has a diameter 1 cm; most gastric ulcers are somewhat larger (1.0 to 2.5 cm in diameter).
- Most ulcers are sharply demarcated and have a round, oval, or elliptical shape.
- Th e mucosa surrounding the ulcer typically is infl amed and edematous.
- Ulcers penetrate the muscularis propria and, in some cases, extend into the serosa or even into the pancreas.
- Fibrous tissue, granulation tissue, and necrotic debris form the ulcer base. During ulcer healing, a scar forms as epithelium from the edges covers the ulcer surface.
- Nearly all duodenal ulcers are benign; up to 10% of gastric ulcers are malignant.
