ABSTRACT

Hydatid cyst results from parasitism by the larval stage of echinococcus species. Echinococcosis is a zoonosis in which humans are an intermediate host of the larval stage of the parasite. Human infection occurs when eggs in dog feces are swallowed. Hydatid cyst, which is situated primary in the neck, is extremely rare. We present a 10-year-old girl with a hydatid cyst located in the retroauricular region that was diagnosed and treated.
