{Reference Type}: Case Reports {Title}: Eosinophilic appendicitis: an insidious and fortuitous diagnosis. {Author}: Llera B;Hanna I;Jureller M; {Journal}: J Surg Case Rep {Volume}: 2024 {Issue}: 6 {Year}: 2024 Jun 暂无{DOI}: 10.1093/jscr/rjae380 {Abstract}: Eosinophilic appendicitis is a rare inflammatory condition characterized by the infiltration of eosinophils into the appendix, which is often misdiagnosed as acute appendicitis given similarities in their clinical presentation. Acute eosinophilic appendicitis: a rare cause of lower gastrointestinal hemorrhage. Within this particular report, we present a case of eosinophilic appendicitis in a 42-year-old female who underwent a laparoscopic appendectomy. The purpose of this report is to increase awareness about this unique condition and emphasize the importance of considering eosinophilic appendicitis as a differential diagnosis in patients with appendicitis-like symptoms whose clinical examination and laboratory findings may suggest otherwise.
