Cystic lymphangioma is also known as cystic hygroma, and this is a congenital malformation of the lymphatic system. Most lymphangiomas are present at birth and they are diagnosed by the age of 2. They are mostly located in the neck or axillary region. The breast as a site of origin is an extremely unusual location, and especially in adults. We report here on a case of cystic lymphangioma in a 36-year-old woman. Physical examination revealed a tender cystic mass in the upper outer quadrant of the right breast. Ultrasonography revealed an irregular hypoechoic mass lesion that was associated with irregular duct dilatation and several enlarged axillary lymph nodes. After the operation, the mass was revealed to be a cystic lymphangioma. Although it is very rare, cystic lymphangioma should be considered in the differential diagnosis of a breast mass in adults.
