Cystic hygroma is a benign disease of the lymphatic system which usually presents in the first years of childhood. A 48 years old male patient was admitted our hospital with left axillary mass. Computerized tomography showed a left axillary cystic lesion about 10x8 cm and a cystic nodule in thyroid right lobe extends towards mediastinum. The axillary lesion was resected and diagnosed as cystic hygroma. In another session, exploration was done via collar incision and cystic thyroid tissue extending towards mediastinum was detected. Subtotal thyroidectomy was applied and pathological diagnose was cystic nodular goitre. During six months follow-up period patient has no problem. We present this case because of its appearance in adulthood, axillary localization and concomitant thyroid lesion which extended towards mediastinum.
