Shrinking birthmarks: bleomycin injections show promise for cystic hygromas in kids
NCT ID NCT07189832
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested injecting bleomycin directly into cystic hygromas (fluid-filled birthmarks) in 30 children aged 1 month to 12 years. The fluid was drained and bleomycin injected, repeated every 4 weeks until the lump shrank. Most children saw significant size reduction, with some having complete shrinkage. This offers a potential alternative to surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bleomycin
- What this could lead to
- If successful, this approach could offer a non-surgical way to shrink cystic hygromas in children, reducing the need for more invasive procedures.
- What could go wrong
- This is a small, completed study with no control group, so results may not apply to all patients. Bleomycin can cause side effects like skin changes or lung issues, though rare with local injection.
