Breast lump as a presentation of a hydatid disease

Abstract

Hydatid disease is a lesion caused by larval form of Echinococcus granulosus and is seen endemically in sheep-rearing countries. Humans are intermediate hosts of this organism. The liver is the first filter that stops about 75% of the embryos and the lungs filter another 10%, leaving only 15% to develop into cysts in other organs of the body.
