Lymphatic malformations revisited: Genetics, clinics and future directions

The clinical management of lymphatic malformations presents challenges due to their rarity, variable presentation, and the potential for recurrence. Dissemination of the latest knowledge in lymphatic malformations is needed to streamline referral pathways and possibly improve patient outcomes. This paper provides a narrative review of the latest developments in aetiopathogenesis, diagnosis and management of lymphatic malformations. Multidisciplinary recommendations from the European Reference Network on Rare Multisystemic Vascular Diseases, Vascular Anomalies working group sets the basis for this review. A literature search was conducted to include the latest research based on authors' preferences. Understanding the aetiopathogenesis of lymphatic malformations is important, as new genetic insights can dictate management strategies. Advancements in diagnostics allow for better differentiation between malformation types and imaging of anatomical infiltrations, where treatment options differ and are more commonly multimodal. Further systematic studies are needed on larger study populations, such as prospective trials and meta-analyses, to improve evidence-based practice.
