Submental primary hydatid cyst: A rare differential diagnosis of midline neck swelling in children.

Summary: Hydatid cysts of the cervical region are extremely rare especially in children and the diagnosis is quite challenging. We report herein a child with a hydatid cyst that was primarily located in the submental region without any pulmonary or hepatic involvement. A hydatid cyst of the neck should be considered as a possible diagnosis while evaluating any slow growing cyst in the cervical region especially in a patient living in endemic areas so as to keep surgical precautions in mind while operating to avoid any dangerous complications such as contamination and a fatal anaphylactic reaction.
