Objective: This study has been conducted so as to contribute to health statistics of hydatid cyst by the data obtained from our clinic, and to discuss hydatid cysts in unusual locations.

Material and Method: Cases diagnosed as hydatid cyst at Dr. Lutfi Kirdar Kartal Research and Education Hospital Pathology Clinic between 2007 and 2015 have been evaluated based on criteria such as age, sex and location.

Results: A total of 364 cases, 209 females and 155 males, have been included in the study. The subjects in the cases are aged between 4 and 81 (mean: 38.84). Regarding the sites, 254 (69.8%) of the cases are located in liver, and 53 (14.6%) in the lung. Fifty-seven cases (15.6%) have been detected in unusual sites other than the lung or liver. The rate of isolated organ involvement, other than the lung and liver, has been found to be 10.3%.

Conclusion: Since hydatid cyst can be found in all the body sites, it should be taken into account in the differential diagnosis of all cystic lesions.
