We report a case of giant fold gastritis identified as Morbus Menetrie
r in a 37 years old male. Clinical, radiological and endoscopic findin
gs suggested the diagnosis, it was established by full-thickness mucos
al biopsy. After a 1-year monotherapy with a proton pump inhibitor the
clinical features of the patient dissappeared. Laboratory findings, e
ndoscopic macroscopic and microscopic signs normalized in the same tim
e. Eventually dysregulation of topical growth factors is the reason fo
r the selective increase of mucus glands in Menetrier's disease. Impro
vement of the mucosal changes after treatment with omeprazol may be ca
used by an influence in this pathogenetic mechanism.
