Primary esophageal Paget’s disease is rare. Only a few case reports have described the intraepithelial papillary capillary loop (IPCL) pattern obtained by magnified Narrow Band Imaging (M-NBI) endoscopy in this rare pathology. This report highlights the usefulness of M-NBI and the successful diagnosis using a large bloc specimen obtained by endoscopic mucosal resection with the cap method (EMR−c). A 53-year-old man was referred to endoscopic examination for dysphagia. The endoscopic image revealed a ring-shaped scarring of the esophagus suggestive for eosinophilic esophagitis. The IPCL pattern by M-NBI endoscopy showed an inflammatory pattern, and the entire epithelium of the esophagus was not stained by Lugol iodine spraying. Based on six biopsies randomly performed, a poorly differentiated adenocarcinoma was diagnosed. Since the M-NBI pattern and the histology were completely different, EMR−c was performed to obtain large bloc specimens for a more detailed diagnosis. The pathological findings revealed extensive Paget’s cells infiltration into the epithelium and multifocal invasion from the mucosa to the submucosal layer with adenocarcinoma. In conclusion, a large bloc specimen by EMR-c might be more useful than a small biopsy for an accurate diagnosis of the rare esophageal Paget’s disease.Key words:  –  – .Abbreviations: EMR−c: endoscopic mucosal resection with cap method; IPCL: intraepithelial papillary capillary loop; LVLs: Lugol-voiding lesions; M-NBI: magnified Narrow Band Imaging; PET-CT: Positron-Emission Tomography and Computed Tomography.

Abstract Background: We are laryngologists, to observe natural phonatory and swallowing functions, in every clinical examination with trans-nasal laryngeal fiberscope (TNLF), before the observation, we use epinephrine to enlarge and smoothen inside common nasal meatus (bottom of nostril), then insert wet swab inside the nose, like a swab culture in nasopharynx. In particular current COVID-19 pandemic situation, this careful technique prevents any complications even nasal bleeding, painfulness, and inducing sneezing. Here we introduce our routine to observe esophageal movement in swallowing in natural setting (sitting position) without anesthesia.Case presentation: A case was 70-year-old female who complained something stuck esophagus or strange sensation below the larynx and pharynx. After enlarge and smoothen inside common nasal meatus we insert the TNLF (slim type ⌀29mm fiberscope, VNL8-J10, PENTAX Medical, Tokyo, Japan.) in a same way. Then observe the phonatory and swallowing movement of vocal folds. To get natural movements we had never used any anesthesia. There was no pathological condition in the pyriform sinus, we asked a patient to swallow the fiberscope. At that timing we push the TNLF and insert the tip a bit deeper simultaneously with swallowing, which make the fiberscope easily enter the esophagus like the insertion of nasogastric tube. Then asked the patient to swallow sip of water or saliva, the lumen of esophagus cleared and enlarged. This makes to observe esophagus easily without any air supply. The esophagus is completely normal except glycogenic acanthosis with tone enhancement scan. Conclusions: The advance point of this examination is easily able to perform in sitting position without anesthesia, also takes only a minute and minimum invasive to observe the physiologically natural swallowing. It is also possible without anesthesia until esophagogastric junction using with a thin type flexible bronchoscopy. In the future, diameter of gastric fiberscope even with narrow band imaging (NBI) function might be gradually getting thinner. Before that time every physician should know this technique. Just insert along the bottom of nose.

Gastric Hyperplastic Polyp

A case of gastric hyperplastic polyp with proliferation of xanthoma cells is reported. The patient was a 69-year-old man who visited our hospital for further evaluation of gastric polyps. Endoscopic examination of the upper digestive tract revealed multiple hyperplastic polyps in the gastric antrum. There was a pedunculated polyp with whitish yellow granules, 7 mm in diameter, arising from the greater curvature of the antrum. Magnification narrow-band imaging endoscopy (GIF-H260Z, Olympus) revealed long microcapillaries in the polyp but did not reveal disappearance of the mucosal microstructure or irregular branched capillaries. Endoscopic mucosal resection (EMR) was performed. Histological examination of the specimen revealed the lengthened gastric foveolae in the superficial portion and tight sheet of foamy histiocytes in the lamina propria. Diagnosis of gastric hyperplastic polyp with proliferation of xanthoma cells was made. There was no evidence of malignancy. It is necessary to know that a gastric hyperplastic polyp may associate with gastric xanthoma, although such association is very rare.
