Description
Park and co-authors report a stomach case of a rare inherited polyp syndrome tied to a SMAD4 gene change. The syndrome causes many soft polyps to grow in the gut. SMAD4 changes often bring severe stomach disease and can link to a vessel disorder. The patient was a 39-year-old woman with lasting anemia and bleeding from the upper gut. She also had a past ovarian tumor. A scope found many stomach polyps, one of them 5 cm wide.
Repeated scope procedures removed polyp tissue, which first looked like common hyperplastic polyps. Gene sequencing then found a harmful SMAD4 change, confirming the diagnosis. The authors urge doctors to weigh inherited syndromes when many stomach polyps appear with anemia.
