摘 要：BACKGROUND Pyloric gland adenoma(PGA)is a recently described and rare *** tumor(SMT)-like PGA is more difficult to diagnose and differentiate from other submucosal *** SUMMARY We present the case of a 69-year-old man with a 10 mm SMT-like elevated lesion with an opening in the upper part of the gastric body,referred to our hospital for further endoscopic *** endoscopy with narrow-band imaging,endoscopic ultrasonography,and complete endoscopic submucosal dissection were performed on the *** findings revealed tightly packed tubular glands lined with cuboidal or columnar cells that had round-tooval nuclei containing occasional prominent nucleoli and an eosinophilic cytoplasm similar to that in non-neoplastic gastric pyloric ***,immunohistochemical analysis showed positive staining for both mucin 5AC and mucin ***,we arrived at the final diagnosis of gastric *** there was no apparent malignant component in this tumor,PGA has been considered a precancerous disease with a high risk of transformation into *** PGA should be considered when detecting gastric SMT-like *** and pathologists should focus on PGA due to its malignant potential.
