Unusual presentations of hydatid cyst

Summary Three patients having hydatid disease with unusual localizations are presented. Although hydatid disease is endemic in Mediterranean countries, it rarely occurs subcutaneously. In our cases they were located on: 1) the right temple of the face, 2) the lateral aspect of the left thigh, and 3) the left mastoid region. There were no real indications to suspect hydatid cysts in the first two cases, whereas it was suspected in the third one. They were removed surgically. There were no complications, and there have been no recurrences.
