The Vascular Anomalies Center (VAC) at Boston Children’s Hospital has established a data registry for patients with rare, complicated lymphatic conditions. The Lymphatic Anomalies Registry is seeking to collect clinical data from patients that could improve our understanding of these diseases, including what complications to expect, which therapies are more effective than others, predictors of disease stability, and/or recurrence and inheritance patterns.

We invite and encourage you to join us in better understanding the nature and treatment of lymphatic anomalies. To learn more about the registry, click here to submit your contact information and someone will get back to you within one week.

Why this registry is important

Individually, lymphatic anomalies are rare disorders, and your physician may have never seen a case like yours. Like many rare disorders, there is not a lot of information about long-term effects and outcomes of these types of conditions or about what the most effective treatments are. Because the few patients with these disorders are spread across the globe, it is very important that we gather patient data from multiple institutions and patients in a centralized registry, with the goal of expediting clinical understanding and improving care.

Collection of data can be particularly difficult with deceased patients, but family members are encouraged to participate. It is important to learn as much as possible from every complication and/or death related to these diseases to better predict who is at risk and when to intervene. This will enable us to provide the more complete care for other patients in the future.

The Vascular Anomalies Special Interest Group within the American Society for Pediatric Hematology/Oncology has identified the Lymphatic Anomalies Registry as an important observational study with participation already from a diverse, international group of patients. We are encouraging participation from all centers that provide care to patients with vascular anomalies, and are working to unite these centers to run innovative clinical trials.


This registry is generously supported by the Lymphatic Malformation Institute, Dana-Farber/Boston Children's Cancer and Blood Disorders Center, CLOVES Syndrome Community, the Knight family, the Malloy family, and Kennedy's Cause.

Regulatory approval

The Lymphatic Anomalies Registry has been approved by the Committee on Clinical Investigation, the institutional review board of Boston Children’s Hospital.
