Hydatid disease of the breast is rare. It can be isolated in the breast or associated with other localizations. A hydatid breast cyst is diagnosed by observing hooklets and scolices obtained by fine needle aspiration cytology. Hydatid disease must be considered in the differential diagnosis of breast disease in endemic regions.

We report a case presenting with a hydatid cyst of the breast as the breast is a rare location for hydatid cyst, and it was diagnosed by fine needle aspiration cytology.
