BackgroundHeterotopic pancreas is a rare developmental anomaly defined as pancreatic tissue found on ectopic sites without contiguity with the main pancreas. An isolated heterotopic pancreas as a cause of bowel intussusception is extremely rare.Case ReportA case of 47-year old male with multiple episodes of melena, constipation and abdominal pain for one year duration is presented. CT eneterography revealed a large circumferential lesion involving the terminal ileum that acted as a leading point to an ileo-ileal intussusception. The resection of the lesion and related bowel segment was carried out. The histopathological examination confirmed the excised lesion as a heterotopic pancreatic tissue.ConclusionsThough a rare entity, heterotopic pancreas should be considered in the differential diagnosis of bowel intussusception.
SummaryBackgroundThe primary neuroendocrine tumors of the gallbladder are very rare, representing 0.2% of all neuroendocrine tumors. The definite diagnosis is incidental in most cases.Case ReportA 60-year-old male patient presented with a one-month history of epigastric pain and jaundice, itching, flushing, cough and wheezing. Ultrasound demonstrated the gallbladder containing multiple stones, with wall thickening and an adjacent liver lesion. Additionally, those structures showed noticeable contrast enhancement in CT and MRI. Histopathological examination revealed a primary gallbladder neuroendocrine tumor.ConclusionsThough a rare entity, primary neuroendocrine tumor should be considered in the differential diagnosis of gallbladder cancers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
