Hydatid disease, caused by larval stage of Echinococcus granulosus, is a common parasitic infection of human and animal. Although liver and lung are the most commonly affected area, hydatid cyst may develop any part of the body. Primary subcutaneous hydatid cyst is extremely rare. We report a case of 54 years old man who presented with palpable mass in scapular region from 3 years ago. Present and past medical history was not significant finding. Pathologic evaluation identified the cystic structure as unilocular hydatid cyst. Primary hydatid disease constitutes a potentially serious differential diagnosis of any subcutaneous mass in endemic area of hydatid disease.
