A Rare Cause of Hypereosinophilia: A Case Report.

Toxocariasis is a parasitic disease caused by the larval stage of Toxocara cati and T. canis, which live in the intestinal system of cats (T. cati) and dogs (T. canis). Infective eggs can enter the gastrointestinal system by the oral route via foods contaminated with feces of dogs or cats or via dirty contaminated hands. The larvae penetrate the small intestine and migrate to visceral organs by systemic circulation. Hypereosinophilia is a common finding in the tissue invasion of parasites. Serological methods are the principle diagnostic methods for toxocariasis. In this study, we reported a toxocariasis patient presented with hypereosinophilia, hepatomegaly, and intestinal involvement. Computed tomography showed diffuse thickening of the ileal bowel loop walls around the umbilicus. Endoscopic ultrasonography revealed an enlarged periduodenal lymph node. Symptoms improved with albendazole treatment with a subsequent flare.

[Renal cyst hydatid]. / Renal Kist Hidatik.

Hydatid cyst disease is an oral transmitted parasitosis caused by the larval form of the Echinococcus granulosus tapeworm that penetrates the intestinal mucosa and reaches the internal organs via the blood and lymphatic stream. Hydatid cyst disease is an important health problem, especially in developing countries, such as Turkey. Renal hydatid cyst is extremely rare, and kidney involvement is seen in only 2% of all cases. In this study, we present two patients with renal hydatid cyst. Hydatid cyst was not suspected before pathological diagnosis in both patients. At first, the patients were suspected of having malignancy, and the treatment modality was made accordingly. When the pathology results revealed hydatid cyst, the treatment of the patients was modified. Renal hydatid disease should be kept in mind in the differential diagnosis of patients presenting with renal cyst in Turkey.
