Diagnostic dilemma with hydatid cysts at unusual sites can lead to complications as sometimes these may present as acute surgical emergency or chronic illness leading to morbidity. The aim of the study is to highlight the fact that this disease should be suspected in cystic lesions involving any organ of the body, especially in endemic areas like India.

Material & Methods:

It is a descriptive study of duration of one year in which all cases of hydatid cysts signed out in the Department of Pathology from June 2017 to May 2018 were included. 25 cases were identified in a period of one year. Haematoxylin and eosin stains sections of 5 micrometres thickness were re-examined in all cases to confirm the diagnosis.


Out of 25 patients, 23 (92%) had single organ involvement and 2 (8%) had more than one organ involved. Liver was involved in 14 patients (56%), either solitary or in association with other organs. Lung involvement was seen in 7 patients (28%). 4 patients (16%) had cyst at extrahepatic site (ovary, pelvis, kidney, pancreas).


A high index of suspicion is required for pre-operative diagnosis of hydatid disease at rare and unusal sites in the body. A possibility of hydatid disease should be considered in the differential diagnosis of cystic swellings present anywhere in the body especially in patients from endemic areas.
