Area of Science:

  • Gastroenterology
  • Pathology

Background:

  • Subepithelial fibrosis is known in the small intestine (collagenous sprue) and colon (collagenous colitis).
  • This report focuses on a rare case of subepithelial fibrosis in the gastric corpus.

Observation:

  • A 15-year-old female presented with chronic gastritis, abdominal pain, and upper GI bleeding.
  • Endoscopic findings included gastric corpus nodularity and erythema.
  • Radiography showed a mosaic-like mucosal pattern in the gastric corpus.

Findings:

  • Biopsies confirmed chronic active gastritis with a distinct thick band of subepithelial collagen.
  • This collagen band was localized beneath surface epithelial cells, not extending deeper.
  • Etiology remains undetermined despite extensive investigation.

Implications:

  • The pathogenesis and prognosis of collagenous gastritis require further study.
  • The relationship between collagenous gastritis and similar conditions in the small intestine and colon is unclear.
  • Current treatments have not shown clinical or pathological improvement.
