Atypical appearances of benign hyperplastic gastric polyps

Area of Science:

• Gastroenterology
• Radiology
• Pathology

Background:

• Epithelial polyps of the stomach are broadly classified into hyperplastic/regenerative polyps and adenomas.
• Hyperplastic polyps are common, non-neoplastic, and rarely undergo malignant transformation.
• Adenomas are true neoplasms with a tendency for malignant transformation.

Purpose of the Study:

• To discuss the radiologic appearances of hyperplastic gastric polyps.
• To highlight atypical findings in hyperplastic gastric polyps.
• To emphasize the importance of histology for clinical management.

Main Methods:

• Review of radiologic appearances of hyperplastic gastric polyps.
• Illustration of atypical findings.
• Correlation with histologic diagnosis.

Main Results:

• Simple hyperplastic polyps can exhibit radiologic features suggestive of adenomas or malignancy.
• Radiologic criteria for gastric adenomas or malignancy may be present in hyperplastic polyps.
• Histologic evaluation is crucial for differentiating benign from potentially malignant lesions.

Conclusions:

• Radiology is essential for initial detection and follow-up of gastric polyps.
• Histologic examination via endoscopy and biopsy is critical for definitive diagnosis.
• Accurate patient management relies on understanding the histological nature of gastric polyps.
