[Sarcoidosis gastropathy: diagnosis and contribution of echo-endoscopy]. / Gastropathie sarcoïdosique: diagnostic et apport de l'écho-endoscopie.

We report a case of gastric sarcoidosis in a 36-year old woman. The clinical and endoscopic ultrasonography findings initially suggested linitis plastica. Subsequently the discovery of unexpected gastric and then, bronchial granulomas after bronchoscopy and bilateral ocular fixation on gallium scanning, led to the diagnosis of sarcoidosis. Endoscopic ultrasonography showed abnormal hypertrophy of the third hyperechoic layer. These findings usually suggest among the etiologies of giant gastric folds, malignant diseases and particularly linitis plastica.
