„Erler-Zimmer GmbH & Co. KG 3D model of chronic gastric ulcer:
- Model Number: MP2076
- Clinical history:
This elderly patient had a long history of „digestive disorders.“ He collapsed and died after suffering a massive stroke. - Pathology:
The specimen is a 2 cm long section of adjacent tissue, including the diaphragm of the stomach, liver and pancreas. The specimen was opened to reveal a large ulcer less than the arcuate at the upper end of the adjacent, near the gastroesophageal junction. Macroscopically, the solidified tissue at the ulcer site is oval, 5-6 cm in diameter, and has slightly raised edges. The base is clean and smooth, with no evidence of bleeding. The gastric wall tissue surrounding the ulcer is hardened by fibrosis that affects the base of the ulcer and spreads to the surrounding mucosa. Being retractile, the fibrosis manages to „crumple“ the gastric mucosa towards the base of the ulcer, causing the folds of the gastric mucosa to contract radially around the solidified tissue (this feature is not seen in ulcerated malignant gastric tumors). This is noticeable in the lower part of the ulcer and to a lesser extent in the upper part. - Additional information:
Patients with stomach ulcers may experience pain that worsens with eating, often described as a burning or dull ache. Other symptoms may include heartburn, vomiting, weight loss, or poor appetite. Complications may include bleeding, perforation, and gastric obstruction. Common triggers include the bacterium Helicobacter pylori and nonsteroidal anti-inflammatory drugs (NSAIDs).
