Here, we report a case of high-grade PanIN with beaded MPD stenoses and extensive intraepithelial lesions. A 72-year-old man was found to have elevated pancreatic enzymes and cystic MPD dilation on abdominal ultrasonography. Contrast-enhanced computed tomography showed diffuse MPD dilation and localized pancreatic atrophy in the pancreatic head. Magnetic resonance cholangiopancreatography revealed cystic dilation of the MPD in the pancreatic body. Endoscopic ultrasonography showed mild MPD stenosis in the pancreatic head, surrounded by hypoechoic area. Endoscopic retrograde cholangiopancreatography revealed multiple bead-like MPD stenoses in the body of the MPD, and a short stenosis in the pancreatic head. Brush cytology of the MPD stenosis in the pancreatic head revealed malignancy, while lavage cytology from the tail side was suspicious for malignancy. Based on these findings, high-grade PanIN extending from the head to the tail was diagnosed, leading to total pancreatectomy. Histological examination demonstrated extensive intraepithelial neoplastic lesions, with high-grade PanIN corresponding to the MPD stenosis in the pancreatic head.","PeriodicalId":10364,"journal":{"name":"Clinical Journal of Gastroenterology","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144539238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present the first case of invasive gastric adenocarcinoma that occurred in a sporadic FGP in an HP-uninfected patient. A 77-year-old man on proton pump inhibitor (PPI) therapy for 6 years developed an enlarged reddish FGP. The absence of atrophic changes in the entire gastric mucosa was confirmed endoscopically and multiple HP tests were negative. After PPI discontinuation, the lesion initially reduced in size from 25 to 15 mm in 1 month; however, malignancy was suspected because of rapid enlargement and persistent discoloration. En bloc resection was performed by endoscopic mucosal resection. Histological examination confirmed FGP and submucosal adenocarcinoma with a depth of approximately 700 μm, negative for lymphovascular invasion, and negative resection margins. A subsequent distal gastrectomy confirmed the absence of residual disease or lymph node metastases. The unusual endoscopic findings of rapid enlargement and reddish tone pushed us to perform endoscopic treatment, which resulted in a correct diagnosis and appropriate treatment.","PeriodicalId":10364,"journal":{"name":"Clinical Journal of Gastroenterology","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the extent of the lesion, surgery was recommended; however, the patient opted for follow-up. After five months, CT and EUS revealed significant tumor growth, raising the suspicion of malignancy. Consequently, subtotal stomach-preserving pancreatoduodenectomy was performed, and postoperative pathology confirmed an intra-ampullary papillary tubular neoplasm (IAPN) with low-grade dysplasia. IAPN is noninvasive and consists of the growth of the ductal epithelium, which is equivalent to adenoma or low-grade adenocarcinoma. Although it is generally characterized by slow growth owing to its noninvasive nature, this case was unique in that it showed rapid progression. Despite being a low-grade IAPN, this case represents a rare instance of rapid enlargement within five months. This case underscores the importance of vigilant monitoring of low-grade IAPN, given its potential for accelerated growth.","PeriodicalId":10364,"journal":{"name":"Clinical Journal of Gastroenterology","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144483408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patient underwent neoadjuvant chemotherapy followed by esophagectomy for advanced esophageal cancer 15 months ago. He reported loss of appetite during a routine outpatient visit, and computed tomography revealed bowel obstruction and intussusception with a tumorous lesion in the transverse colon. Positron emission tomography did not reveal any abnormal accumulation in other areas. Based on these findings, a transverse colectomy was performed. Pathological examination of the resected specimen revealed squamous cell carcinoma components in the normal colonic mucosa, which were diagnosed as colonic metastases from the esophageal cancer. Postoperatively, the patient recovered uneventfully and commenced adjuvant therapy with capecitabine monotherapy, which was later discontinued at the patient's request. Four months post-surgery, liver metastasis developed, and the patient underwent immunochemotherapy. Colorectal metastasis from esophageal cancer is relatively rare, making preoperative diagnosis challenging.
