Ménétrier disease: a rare cause of severe chronic diarrhea difficult to diagnose with response to treatment with octreotide.

We present the case of a 71-year-old male with difficult to manage severe chronic diarrhea, who after multiple tests was finally diagnosed with Ménétrier's disease and had clinical improvement with treatment with intramuscular octreotide. A high degree of clinical suspicion is essential to diagnose this entity, exclude similar entities and the correlation of clinical, analytical, endoscopic, radiological and histological data.
