title: Unusual localization of a primary hydatid cyst: a subcutaneous mass in the paraumbilical region.
abstract: Hydatid cyst disease caused by Echinoccus granulosus is not a rare disease and mostly localized in liver and lung. The localization of the disease in the subcutaneous paraumbilical region without any other organ involvement is a unique existence that we present. A 63-year-old Turkish male complaining of abdominal distention and pain had an abdominal mass for one year. When the patient came to our Clinic, we detected a 4x5 cm mass in the left quadrant- paraumbilical region by using ultrasonography. Complete surgical resection of the mass was performed with uneventful post-operative recovery. Histopathological examination of the surgical specimen demonstrated a multive-sicular hydatid cyst. When a subcutaneous cystic mass is detected in a patient, regarding the region where he lives and endemicity, hydatid cyst should be considered.
