A Case of Early Gastric Cancer That Endoscopic Findings Changed Morphologically from Type 0-Iia to Type 0-Iic in a Short Period
Progress of Digestive Endoscopy(2015)
摘要
The patient was a 75-year-old woman. An esophagogastroduodenoscopy (EGD) performed for examination of an anemia revealed an elevated and faded lesion (type 0-IIa) of 20-mm diameter located on the anterior wall of the upper gastric body. The EGD before the endoscopic submucosal dissection (ESD) performed 10 weeks later showed that the lesion had changed to a reddened and depressed lesion (type 0-IIc) . The ESD was performed another one week later, pathological examination of the removed lesion revealed that the mucosa was omitted mostly and almost no cancer cell existed in the depressed lesion and cancer cells existed in only the part of the surrounding protuberance part. Thereby we suggested that the protuberant part of the tumor was spontaneously fallen off.
