Breast Recurrent Hydatid Cyst Disease

: Introduction: Hydatid cyst is a zoonotic disease seen in endemic areas. It is an important health problem in our country and especially in our Eastern and South-eastern Anatolia Region. Involvement of isolated breast tissue is very rare in hydatid cystdisease. As far as we know, isolated recurrent breast cyst hydatidosis has not been found in the literature. CASE REPORT: We aimed to present the case of a patient who was diagnosed with recurrent isolated cyst hydatid in the same breast, operated on because of hydatid cyst in the right breast 9 years ago. CONCLUSION: A hydatid cyst should be considered, particularly in endemic regions, in the differential diagnosis of cystic masses of the breast. If the patient has previously undergone surgery for breast cyst hydatid disease, recurrent cyst hydatid disease should be considered at the differential diagnosis.
