Lymphoreticular hyperplasia of the stomach (pseudolymphoma)

Area of Science:

• Gastroenterology
• Pathology
• Radiology

Background:

• Gastric lymphoreticular hyperplasia is a rare condition.
• It is frequently misdiagnosed as gastric carcinoma or lymphoma.

Purpose of the Study:

• To report three cases of gastric lymphoreticular hyperplasia with long-term follow-up.
• To highlight diagnostic challenges and suggest key features for identification.

Main Methods:

• Histological confirmation of gastric lymphoreticular hyperplasia.
• Long-term clinical and radiological follow-up of three patients.

Main Results:

• The condition was radiologically confused with ulcerating carcinoma.
• Pathological examination was often mistaken for malignant lymphoma.
• Key features include a large ulcer, surrounding mass, thick rugal folds, and associated ulcers.

Conclusions:

• Gastric lymphoreticular hyperplasia presents diagnostic challenges.
• Specific radiological findings, while not definitive, should raise suspicion for this condition.
