OBJECTIVE: An accurate diagnosis of a subepithelial tumor (SET) using endoscopic ultrasound (EUS) without tissue acquisition is difficult. Treatment plan for a SET may be influenced by endoscopic tissue diagnosis. We aimed to clarify the clinical outcomes of direct endoscopic biopsy for SET after removal of the overlying mucosa. METHODS: We evaluated the medical records of 15 patients. All patients underwent direct endoscopic biopsy for a SET larger than 20 mm (involving proper muscle layer) after removal of the overlying mucosa...

BACKGROUND: Gastrointestinal stromal tumors are the most common mesenchymal neoplasms affecting the gastrointestinal tract. The stomach is the most common location to be affected, and the rectum one of the rarest, but the whole gastrointestinal tract remains susceptible. Gastrointestinal stromal tumors account for only 0.1% of rectal tumors. Currently, endoscopic ultrasound plays an essential role in the diagnostic process of gastrointestinal stromal tumors, especially when the affected sites have a worse outcome and higher morbidity rates...

Using EUS, it is practicable to diagnose Subepithelial lesions (SEL) with originating layer, echo level, and internal echo pattern etc. Lipoma, lymphangioma, and cyst have characteristic features, therefore they have no need for EUS-FNA. Ectopic pancreases and glomus tumors, which are originated from 3(rd) and 4(th) layer, are frequently seen in the antrum. Although ectopic pancreases located in the fundus or body are large and originated from 3(rd) and 4(th) layer (thickening of 4(th) layer). Each Subepithelial lesions has each characteristic finding...

BACKGROUND AND OBJECTIVES: Gastrointestinal stromal tumors (GISTs) represent the largest group of subepithelial tumors (SET) of the upper gastrointestinal (GI) tract. They may show malignant behavior, in contrast to other SET. Endoscopic ultrasound (EUS) is frequently used to characterize SET. With the introduction of contrast-enhanced ultrasound (CEUS) into EUS (CE-EUS), distinct enhancement patterns can be detected. In the presented study, the characteristic features of CE-EUS in GIST are analyzed and compared with those of other SET...

The term cystic nephroma has traditionally been used to refer to 2 neoplasms, a lesion in adults that is now thought to be part of the spectrum of mixed epithelial stromal tumor (MEST) and a pediatric lesion that has been associated with mutations in the DICER1 gene. A direct detailed morphologic, immunohistochemical, and genetic comparison of these 2 lesions has not been performed. In this study, we compare the morphologic features, immunoreactivity for estrogen receptor and inhibin, and DICER1 genetic status of 12 adult cystic nephroma/MEST (median age 50...

BACKGROUND AND AIMS: Subepithelial lesions are found in about 1% of all EGD procedures, and GI stromal tumors are a type of subepithelial lesion commonly encountered. Although the majority of subepithelial lesions are benign, GI stromal tumors have malignant potential, making a definitive diagnosis important. Currently, the criterion standard for the diagnosis of GI stromal tumors is EUS-directed FNA (EUS-FNA). The definitive diagnosis of GI stromal tumors relies on immunohistochemical staining, which depends on enough tissue being submitted to the pathologist...

Some biliary diseases mimic pancreatic diseases pathologically as well as pathogenetically. Such diseases can be called "biliary diseases with pancreatic counterparts". Biliary intraepithelial neoplasm (BilIN), intraductal papillary neoplasm of bile ducts (IPNB), hepatobiliary mucinous cystic neoplasm (hMCN), and IgG4-inflammatory pseudotumor represent the biliary counterparts of pancreatic intraepithelial neoplasm (PanIN), intraductal papillary mucinous neoplasm of pancreas (IPMN), pancreatic MCN, and mass forming type 1 autoimmune pancreatitis (AIP), respectively...

BACKGROUND: - Gastric subepithelial lesion is a relatively common diagnosis after routine upper endoscopy. The diagnostic workup of an undetermined gastric subepithelial lesion should take into consideration clinical and endoscopic features. OBJECTIVE: - We aimed to investigate the association between patients' characteristics, endoscopic and echographic features with the histologic diagnosis of the gastric subepithelial lesions. METHODS: - This is a retrospective study with 55 patients, who were consecutively diagnosed with gastric subepithelial lesions, from October 2008 to August 2011...

Isolated mediastinal tuberculous lymphadenitis is clinically rare. Its clinical presentation may mimic an esophageal submucosal tumor by extrinsic compression. A 26-year-old woman was referred to our hospital for an esophageal subepithelial tumor. A 15×10 mm sized subepithelial lesion was found 30 cm from the upper incisors on esophagogastroduodenoscopy. We diagnosed the lesion as a submucosal tumor, and performed endoscopic ultrasonography-guided fine needle aspiration for a pathologic diagnosis. The histologic examination revealed granulomatous inflammation consistent with tuberculosis...

BACKGROUND AND OBJECTIVES: Contrast-enhanced harmonic endoscopic ultrasound (CEH-EUS) is a novel technology that can identify subepithelial tumors (SETs) by detecting the degree of enhancement, but whether CEH-EUS can predict the malignancy risk of gastrointestinal stromal tumors (GISTs) remains unclear. The aim of our study was to evaluate the diagnostic accuracy of CEH-EUS and its ability to discriminate among SETs and predict the malignancy risk of GISTs. MATERIALS AND METHODS: We retrospectively included patients with suspected subepithelial lesions who underwent CEH-EUS preoperatively...

OBJECTIVE: Laparoscopy-assisted endoscopic full-thickness resection (LAEFTR) has been suggested as an alternative to laparoscopic wedge resection in the treatment of gastric subepithelial tumors (SETs). It is expected to minimize the resection of the tissue surrounding the tumors and maintain the function of the remnant stomach. Here, we performed a prospective pilot study to evaluate the efficacy of laparoscopy-assisted endoscopic full-thickness resection (LAEFTR) for patients with gastric SETs...

Autoimmune paraneoplastic and neoplasm-associated skin syndromes are characterized by autoimmune-mediated cutaneous lesions in the presence of a neoplasm. The identification of these syndromes provides information about the underlying tumor, systemic symptoms, and debilitating complications. The recognition of these syndromes is particularly helpful in cases of skin lesions presenting as the first sign of the malignancy, and the underlying malignancy can be treated in a timely manner. Autoimmune paraneoplastic and neoplasm-associated bullous skin syndromes are characterized by blister formation due to an autoimmune response to components of the epidermis or basement membrane in the context of a neoplasm...

Incidental gastric subepithelial tumor (SET) is frequently found during endoscopy. Although endoscopic ultrasonography (EUS) can provide useful information, its diagnostic accuracy varies. Most of the potentially malignant tumors observed on EUS are hypoechoic lesions. Therefore, we aimed to investigate the diagnostic accuracy of EUS for hypoechoic lesions located in the submucosa or proper muscle layer. We also evaluated various characteristics for potential associations with diagnostic accuracy.A retrospective review was conducted of the medical records of 99 patients who were diagnosed with gastric SET and who underwent EUS with pathologic confirmation between March 2008 and April 2015...

Endoscopic ultrasound (EUS) plays an important role in imaging of the mediastinum and abdominal organs. Since the introduction of US contrast agents (UCA) for transabdominal US, attempts have been made to apply contrast-enhanced US techniques also to EUS. Since 2003, specific contrast-enhanced imaging was possible using EUS. Important studies have been published regarding contrast-enhanced EUS and the characterization of focal pancreatic lesions, lymph nodes, and subepithelial tumors. In this manuscript, we describe the relevant UCA, their application, and specific image acquisition as well as the principles of image tissue characterization using contrast-enhanced EUS...

Endometriosis is a benign gynecologic disease, characterized by the presence and growth of functional endometrial-like tissue outside uterus. This ectopic endometrial tissue is most commonly found in the peritoneum, ovaries and uterosacral ligaments, but extremely rarely there is involvement of the appendix or cecum. Here we report a case of cecal endometriosis presenting as a subepithelial tumor diagnosed by surgical excision.

Most esophageal lipomas are discovered incidentally and are small and asymptomatic. However, large (>4 cm) lipomas may cause various symptoms, including dysphagia, regurgitation, or epigastric discomfort. We present a 45-year-old woman with intermittent sudden choking and globus pharyngeus. Upper gastrointestinal endoscopy and endoscopic ultrasound revealed an approximately 10.0×1.5 cm pedunculated subepithelial tumor in the upper esophagus, identified as the cause of her symptoms. A thoracic computed tomography scan revealed a fat attenuated longitudinal mass along the upper esophagus, suggestive of a lipoma...

Granular cell tumors (GCTs) are soft tissue neoplasms that originate from Schwann cells. They occur predominantly in the oral cavity, skin, and breast tissues. Gastrointestinal GCTs are very rare, accounting for only eight percent of all GCTs, most of which are located in the esophagus. Endoscopic ultrasound has been a breakthrough in diagnosing GCTs because it provides precise information on the depth of tumor invasion, thus narrowing the differential diagnosis of subepithelial lesions in the esophagus. However, the definitive diagnosis requires histological confirmation of the lesion...
