Toxocariasis Presenting with Hypereosinophilia and Lymphadenopathy: A Case Report.

Human toxocariasis is a parasitic disease transmitted to humans by ingestion of Toxocara spp. larvae. Rural area residents and children have higher risk for this parasitic infection. The disease is frequently asymptomatic; however, it may cause symptoms such as cough, fever, headache, myalgia or other conditions such as lymphadenopathy and granulomatous hepatitis. Albendazole is used for the treatment of toxocariasis diagnosed by serologic and immunological methods. Herein, we report two cases of toxocariasis that were investigated due to hypereosinophilia and lymphadenopathy for a long time.
