Cystic lymphangiomas are lymphatic malformations rather than true neoplasms. These are mainly childhood lesions. Involvement of the breast is extremely uncommon, and to the best of our knowledge only 17 such cases have been found in the literature. Breast involvement is even rarer in children, as only four of the reported cases are in the pediatric age group. We herein report a case of cystic lymphangioma of the breast in an 8-year-old male child, which was treated by excision. A review of the reported cases is also presented.
