BACKGROUND AND STUDY AIMS: @entity1776 of the esophagus are rare @entity5 . A definite diagnosis is achieved by endoscopic biopsies in only 50% of cases. Endoscopic ultrasonography (EUS) is the best procedure in the evaluation of @entity1820 . The aim of this study was to describe the endosonographic findings of @entity1776 . METHODS: From January 1989 to March 1994, 15 @entity1 with 21 @entity1776 which had negative biopsies were examined by EUS (Olympus GF UM3 or GF UM20,7,5 and 12 MHz). In five cases, the @entity5 was also studied with a 20 MHz Olympus miniprobe. The final histological diagnoses were obtained by subsequent endoscopic snare resection in 20 cases and surgically in one case. RESULTS: The endosonographic features (with the GF UM3 or GF UM20) of @entity1776 were: a) a @entity5 size of less than 2 cm in 95% of cases; b) an hypoechoic solid pattern in 100% of cases; c) a @entity5 arising in the inner layers in 95% (second echo-poor layer n=15; third echo-rich layer n=5). In one case, the endosonographic finding was transmural malignant infiltration of the esophageal wall (histologically confirmed). CONCLUSION: When a granular cell @entity5 of the esophagus is suspected, EUS can show the inner layer location of the @entity5 and thus contribute to planning the endoscopic resection or follow up. When the @entity5 also invades the outer layers, EUS can contribute to planning the surgical resection.
