Idiopathic hypereosinophilic syndrome presenting with liver mass: Report of two cases: Idiopathic hypereosinophilic syndrome and liver mass

Herein, we report on two cases of hypereosinophilic syndrome presenting as liver mass. One patient was a 22-year-old woman presented with fever, upper abdominal pain, nausea/vomiting and a mass in the right liver lobe. The second patient was a 54-year-old man who presented with nausea and abdominal pain with significant weight loss. He had multiple lesions in both liver lobes. Both patients had eosinophilia that was not attributed to other causes such as allergy or parasites. The patients were treated with glucocorticosteroid and improved clinically. Imaging and laboratory abnormalities resolved.
