Pediatric breast lymphatic malformation with recurrent presentation in an adolescent female

This case report summarizes a rare case of left chest wall/breast lymphatic malformation or cystic lymphangioma in a female child of 18 months with multiple late recurrences in adolescence. By maternal history, the mass was excised initially, but the patient presented at age 15 and 17 years for recurrences and associated symptoms. Comments focus on a complex clinical history and treatment management of patient symptoms and concerns. Breast sparing treatments were employed with sclerotherapy and the T lymphocyte inhibitor, Sirolimus (Rapamune).
