title: Primary subcutaneous inguinal hydatid cyst: diagnosis by fine needle aspiration cytology.
abstract: Hydatid disease or human cystic echinococcosis, recognized by ancient scholars such as Hippocrates, Galen and Rhazes, is one of the oldest diseases known to man. Though hydatid cyst may develop in almost any part of the body, a solitary primary subcutaneous localization is an extremely rare entity. We herein report a case of primary subcutaneous inguinal hydatid cyst which was diagnosed by fine needle aspiration cytology. Radiological examination done subsequently corroborated with the cytodiagnosis of Hydatid cyst and did not show involvement of any other organ or site. Histopathological examination of surgically removed cyst confirmed the diagnosis of Hydatid cyst. Hydatid disease should be considered in the differential diagnosis of all unusual swellings in soft tissues, especially in regions where the disease is endemic.
