Giant abdominal stromal cell tumour diagnosed at endoscopic ultrasonography: is there a need for systematic use of endoscopic ultrasonography in submucosal gastric tumours?

Abstract A giant abdominal stromal cell tumour was diagnosed at endosonography performed for a relatively small gastric submucosal lesion. Although the case is rare, it draws attention to the need for systematic investigations with endoscopic ultrasonography in any submucosal lesion.
