title: Primary hydatid cyst presenting as a mass in the supraclavicular region: an unusual case report and literature review.
abstract: Hydatid disease, also known as echinococcosis or hydatidosis, is an infectious disease caused by the cestode Echinococcus. Echinococcus granulosus is the most common Echinococcus species affecting human beings. It may affect any organ and tissue in the body, in particular the liver and lung. Musculoskeletal or soft tissue hydatidosis accounts for about 0.5%-5% of all echinococcal infections in endemic areas, and is almost always secondary to the hepatic or pulmonary disease. Even in regions where echinococcosis is endemic, hydatidosis of cervicofacial region is extremely rare. Herein, we present an exceptionally rare case with an unusual localization of primary hydatid cyst in the right supraclavicular region of the neck without involvement of the lungs or pleura.
