Introduction:
Lymphatic malformations (LMs) are rare vascular anomalies predominantly affecting infants, which can be debilitating or life-threatening when complicated with intralesional bleeding or infection. Effective and safe management strategies are essential in such cases.
Case Presentation:
We report a case series involving four Chinese neonates with life-threatening LMs, initially treated with oral sirolimus. All patients achieved rapid relief and sustained remission, using a lower sirolimus dosage than previously recommended. Furthermore, adverse events were rarely recorded during follow-up.
Conclusion:
Sirolimus can be considered a promising choice for neonates with intricate and life-threatening LMs. Initiation with a reduced sirolimus dose is advisable.
