Primary subcutaneous cyst hydatid of abdominal wall: a case report

Abstract

Human body is an intermediate host for Echinococcus granulosus which is a cestode causing hydatid disease. The most common type is E. Granulosus. E. Granulosus most often affects the liver and the lung. Primary subcutaneous cyst hydatid without involving other organs is extremely rare. A 60-year-old Turkish woman came to our hospital with a growing mass in the left periumblical region of the abdominal wall. In the superficial tissue ultrasonography a cystic mass measuring 3×2 cm was detected in the subcutaneous tissue of left periumblical region of the abdominal wall and it was doubtful for hydatid cyst. The patient had no history of surgery for a hydatid cyst in any other organ and the hydatid serology was negative. The cyst was surgically, and carefully excised. Macroscopic exploration suggested a hydatid cyst with its germinative membrane and the histopathological examination of the specimen was reported as a hydatid cyst. Hydatid cyst should be considered when a subcutaneous cytic mass is detected in a patient living in the region where the disease is endemic. The best treatment is complete removal of the cysts.
