Primary Hydatid Cyst in the Axillary Region: A Case Report

Axillary region is one of the areas where primary hydatid cyst is rare. In this study, we present a case of isolated axillary hydatid cyst in a 40 year-old female patient having applied to our polyclinic with swelling and pain on right axillary. During the breast examination of the patient on right axillary, well-circumscribed semi-mobile mass lesion was detected. On mammary ultrasonography, both breasts were natural. There was necrotic lymphadenopathy on right axillary that was roughly 10×10 cm sized, and locally included cystic patency. Axillary LAP excision was planned for histopathologic diagnosis. Patient was taken to the operation. After it was understood that cyst was hydatic, it was excised with germanium membrane by encircling it with savlon compresses. In order to differentiate primary secondary on post-operative patient, the patient was taken to thoracic and abdomen tomography. No cystic lesions were detected on tomography. Having no problems on follow-ups, the patient was discharged on 3 post-op days with recommendations, and with starting albendazole 10 mg/kg.
