Abstract
|
|
|
Acute eosinophilic appendicitis (AEA) is defined as eosinophilic infiltration of the muscular layer of the appendix instead of neutrophils.
The symptoms of this disease are similar to those of acute suppurative appendicitis. On the other hand, it can present as a lower gastrointestinal hemorrhage. This paper reports a case of an elderly man with an appendiceal hemorrhage due to AEA. The diagnosis was made by colonoscopy during an evaluation of hematochezia. The patient underwent a laparoscopic partial cecectomy. The histology findings revealed ulceration and marked eosinophilic infiltration of the muscularis propria of the appendix with accompanying edema. Although appendiceal hemorrhage due to AEA is extremely rare, clinicians should consider it in a differential diagnosis.
