Inverted hyperplastic polyp (IHP) is a rare disease characterized by the downward growth of proliferative mucosal components into the submucosal layer. It is often misdiagnosed as other submucosal tumors and accurate diagnosis requires pathological examination. Most patients with IHP have no clinical symptoms and some have non-specific symptoms, such as abdominal distension, abdominal pain and even anemia. IHP is treated via endoscopic mucosal resection or endoscopic sub-mucosal section. The present study reported a case of IHP and discussed its clinical manifestations, clinicopathological diagnosis, differential diagnosis and treatment to improve our understanding of the disease.
