title: Cytodiagnosis of isolated primary hydatid cyst of breast masquerading as a breast neoplasm: A rare case report.
abstract: Hydatid cyst in the breast is very rare and unusual for its location. Reported incidence of hydatid cyst in the breast is 0.27% in the literature. Herein, we report a case of hydatid cyst of breast in a 65-year-old female who presented with painless, slowly growing lump in the breast mimicking breast neoplasm clinically. Radiological investigations such as ultrasonography and mammography may be helpful but not conclusive. Preoperative fine-needle aspiration cytology (FNAC) diagnosis was consistent with hydatid cyst of breast and was without any complications. Histopathological examination of lumpectomy specimen confirmed the diagnosis of hydatid cyst of breast. High suspicion of this entity should be there in the differential diagnosis in the evaluation of breast lump in endemic as well as in migrant population in nonendemic areas.
