A CASE OF INFLAMMATORY POLYP WITH PSEUDOSARCOMATOUS GRANULATION AT THE ESOPHAGOGASTRIC JUNCTION

Abstract

A 60-year-old woman was referred to our hospital for a polyp at the esophagogastric junction. Endoscopic examination revealed a semipedunculated polyp with heterogeneous color pattern about 7mm in diameter. Since biopsy specimens revealed microscopically severe inflammatory change and bizarre atypical stromal cells, pseudosarcomatous granulation was suspected. About a month after endoscopic examination, the polyp was removed endoscopically at another institution. Removed specimen showed an inflammatory polyp with pseudosarcomatous granulation. Such lesion may be often misdiagnosed as malignancy when inflammatory change is severe.
