PathologyOutlines.com Owner and Founder.
Article Synopsis
- The small intestine and ampulla can develop various benign tumors and tumor-like diseases that may resemble cancer, highlighting the need for pathologists to have a comprehensive understanding of these conditions.
- Key examples of these benign issues include Brunner gland lesions, different types of polyps, and various mesenchymal proliferations like inflammatory fibroid polyps and leiomyomas.
- The review aims to clarify the histopathological features of these benign conditions to aid pathologists in making accurate diagnoses and differentiating them from malignant tumors.
Endoscopic submucosal dissection for the treatment of a large inflammatory fibroid polyp in the gastric antrum prolapsing into the duodenum: A case report.

Rationale: Inflammatory fibroid polyp (IFP), also known as Vanek tumor, is a rare, benign gastrointestinal lesion characterized by its inflammatory and fibroid histological features. IFP is often discovered incidentally during endoscopic examinations. It is exceedingly rare for an IFP to prolapse into the duodenum and results in incomplete obstruction of the pylorus.

Background And Aims: This pilot study aimed to evaluate safety and tissue sampling from subepithelial lesions (SEL) in the upper gastrointestinal tract with a novel electric motor driven endoscopic ultrasonography (EUS)-guided 17-gauge (G) size core needle biopsy (CNB) instrument.
Methods: An investigator-led prospective open label, performance and safety control study, including seven patients (female = 4, median 71 y, range 28-75) with a determined SEL (median size 30 mm, range 17-150 mm) in the upper digestive tract (stomach = 6, duodenum = 1) were eligible and later followed up 14 days after index procedure. All investigations were completed according to protocol with three FNB 22-G passes with four fanning strokes and two EndoDrill 17-G passes with three fanning strokes.
Endoscopic Ultrasonography-Guided Fine-Needle Aspiration for Duodenal Subepithelial Lesions Showing a Hypoechoic Mass on Endoscopic Ultrasound Imaging.

Department of Medical Research Promotion, Aso Iizuka Hospital, Iizuka, Japan.
Background/aims: For duodenal subepithelial lesions showing a hypoechoic mass on endoscopic ultrasound imaging, the utility of endoscopic ultrasound-guided fine-needle aspiration and the frequency of histological types have not been the focus of previous literature. This study aimed to clarify this.
Materials And Methods: This prospective observational study enrolled 22 consecutive patients who underwent endoscopic ultrasoundguided fine-needle aspiration for duodenal subepithelial lesions with hypoechoic mass on endoscopic ultrasound.
