Eosinophilic peritonitis in a patient with liver cirrhosis: A case report

Eosinophilic gastroenteritis (EG) is a gastrointestinal disease characterized by abnormal infiltration of eosinophilic cells in the gastrointestinal tract, excluding known causes of eosinophilia. Eosinophilic peritonitis (EP) is rare and is considered by most scholars to be a systemic or local allergy to exogenous or endogenous allergens. It is a clinical manifestation of eosinophilic gastroenteritis involving the serosal layer. Hereby, we report a case of EP in a patient with liver cirrhosis. A 32-year-old man was admitted to our hospital for intermittent fatigue, abdominal distension and abdominal pain. On account of clinical feature and pathological results of peritoneal puncture biopsy, excluding other causes of peripheral eosinophilia, the diagnosis of EP with hepatic cirrhosis was established. The possibility of EP should be paid great attention to patients with cirrhosis with peritonitis. Gastrointestinal endoscope biopsy, laparoscopy or peritoneal puncture biopsy are conducive to the diagnosis and differential diagnosis. Therefore, once the disease is suspected, gastrointestinal endoscope biopsy should be performed actively, and multiple pathological samples should be taken to contribute to diagnosis and treatment. Laparoscopy or peritoneal puncture biopsy is of vital significance for definitive diagnosis.
