Description

A 27-year-old man was admitted to the hospital because of chronic onset of right lower abdominal pain. Colonoscopy was performed, because pain and tenderness were present over the right lower quadrant and a mass 2cm in size was palpable at the same region. An elevated lesion was observed at the orifice of appendix by a colonoscopy. Inflammatory disease in the cecum or chronic appendicitis was suspected. However, diffuse wall thickness of the appendix especially submucosal layer was observed but no elevated lesion was seen at the orifice of appendix by a ultrasonography of the abdomen. Chronic appendicitis was diagnosed but to make differential diagnosis from other diseases, an appendectomy and a partial resection of the cecum were performed. It was chronic inflammtion and no change of neoplasm was observed in histological examinations. We consider that the elevated lesion on the colonoscopy was formed by inflating the colon due to sclerosing change of the appendix and the fixation with the abdominal wall.
