Idiopathic hypereosinophilic syndrome presenting with multiple organ damage: A case report.

RATIONALE

Idiopathic hypereosinophilic syndrome (IHES) is a rare disease in which patients which present with eosinophilia-associated damage. Previous studies focused on organ damage from increased eosinophilic granulocytosis. We report IHES in a patient who presented with multiple organ damage (MOD).

PATIENT CONCERNS

A 52-year-old male presented with MOD, including myocardial damage suggestive of myocardial infarction, cardiac tamponade, respiratory failure, skin damage, and gastrointestinal damage.

DIAGNOSES

The absolute eosinophil count was 12,920/mm, much higher than occurs in other diseases associated with eosinophilia (1500/mm), and suggesting a diagnosis of IHES.

INTERVENTIONS

Prednisone combined with hydroxyurea.

OUTCOMES

At 6 months after completion of drug treatment, the patient had no chest pain or dyspnea, and the results of a blood panel, chest computed tomography, and gastroscopy were normal.

LESSONS

MOD is very rare in patients with IHES. Patients receiving prompt diagnosis and treatment have very good prognoses.
