AbstractAbstract PDFPubReaderePub

Schwannomas of the gastrointestinal (GI) tract are rare subepithelial tumors comprising approximately 3.3% to 12.8% of all mesenchymal tumors of the GI tract. On endoscopic ultrasound (EUS) they are seen as hypoechoic tumors arising most commonly from the 4th proper muscle layer. Although EUS helps to distinguish tumor characteristics, tissue sampling is required for differentiation with other more common tumors such as GI stromal tumors. Both EUS-guided fine needle aspiration and EUS-guided trucut biopsy (EUS-TCB) can be used for tissue sampling. However, only EUS-TCB allows core biopsy and a high yield of immunohistochemical staining. We report a case of a gastric schwannoma diagnosed by EUS-TCB.

Endoscopic Resection of Hypopharyngeal Squamous Cell Carcinoma

AbstractAbstract PDFPubReaderePub

Hypopharyngeal cancers are often diagnosed at an advanced stage and have a poor prognosis. Even when they are diagnosed at an operable stage, surgery often results in substantial morbidity and decreased patients' quality of life. Although the endoscopic diagnosis of early hypopharyngeal cancer is difficult, recent developments in advanced imaging endoscopy have enabled easier diagnosis of these lesions. Endoscopic resection of early hypopharyngeal cancer is a potential minimally invasive treatment that can preserve the function and quality of life of patients. Reports of this procedure are limited, however. We report a case of hypopharygeal cancer treated with endoscopic resection.
