[Mammary hydatid cyst diagnosed by fine needle aspiration]
1Laboratoire d'anatomie et de cytologie pathologiques, CHU Habib-Bourguiba, 3029 Sfax, Tunisie.
Introduction:
Echinococcal involvement of the breast is extremely rare and usually not included in the differential diagnosis of breast lumps.
Observation:
This is an unreported case of a 56-year-old woman who came with a 3 cm mammary mass. Mammography showed a dense well-circumscribed lesion with calcifications. The diagnosis was established by fine needle aspiration and confirmed by pathological study.
Conclusion:
Hydatid cyst of the breast is rare. The diagnosis by fine needle aspiration is controversial. The treatment is based on complete excision of the cyst.
