Cycle 1

Complex Lymphatic Anomalies (CLAs) are a group of rare diseases that are characterized by abnormal growth of lymphatic vessels that may involve multiple organ systems, including lung, spleen, soft tissue and bones. CLAs include: Gorham Stout Disease (GSD), Generalized Lymphatic Anomaly (GLA), Kaposiform Lymphangiomatosis (KLA) and Central Conducting Lymphatic Anomaly (CCLA).n
