Classification of erosions of the stomach and duodenum:

Primary erosions.
Secondary erosions (associated with the underlying disease).
Erosions as a manifestation of a malignant or systemic process in the gastric mucosa (malignant erosions in cancer, lymphoma, Crohn's disease, etc.).
Benign erosions:
1. Acute erosions (hemorrhagic).
2. Chronic erosions, single and multiple.
3. Chronic erosive (lymphocytic) gastritis.
4. Erosive hemorrhagic gastritis and duodenitis.

Acute erosions include flat erosions whose epithelialization period does not exceed 2-7 days; chronic erosions include erosions that do not undergo reverse development within 30 days or more.
