title: Endoscopic ultrasonography in gastric lymphoma.
abstract: Endoscopic ultrasonography (EUS) was performed in 82 patients with primary gastric lymphoma. EUS correctly diagnosed lymphoma in 76/82 patients, with a sensitivity of 93%. Positive predictability was 91%, specificity 98%, and negative predictability 98%. Diagnostic accuracy was 97%. In the evaluation of lymphoma, depth invasion EUS was correct in 87% of cases. EUS disclosed metastatic perigastric lymph nodes in 15/27 patients, with a sensitivity of 56%. Positive predictability was 100%, specificity 100%, and negative predictability 82%. Diagnostic accuracy was 85%. Differential diagnosis with EUS among lymphoma, linitis plastic and Ménétrier's disease was difficult. Large particle biopsy must be considered when EUS diagnosis of these diseases remains uncertain.
