Diagnostic challenge of gastritis cystica profunda with secondary abscess formation: A case report.

BACKGROUND

Gastritis cystica profunda (GCP) is a rare submucosal gastric lesion characterized by the extension of cystically dilated gastric mucosal glands into or below the muscularis mucosa, often due to various underlying causes. Typically, asymptomatic or associated with mild symptoms, GCP is most commonly discovered incidentally during surgery or endoscopy. To the best of our knowledge, this is the first documented case of GCP accompanied by acute inflammation and abscess formation.

CASE SUMMARY: A 37-year-old woman presented with upper abdominal pain. Laboratory tests showed elevated inflammatory markers and carbohydrate antigen 19-9 levels. Gastroscopy revealed a submucosal bulge. Based on enhanced computed tomography findings, an ectopic pancreas with cyst was suspected. Clinically, we decided to perform distal gastrectomy. Postoperative pathology confirmed that the patient had GCP complicated by acute inflammation and abscess formation. The patient had an uneventful postoperative recovery.

CONCLUSION

This case provides information on new complications of GCP and emphasizes the diagnostic value of enhanced computed tomography.
