Summary

This study tested a cream containing sirolimus on rare skin growths called microcystic lymphatic malformations, which can ooze, bleed, and cause pain. 55 children and adults applied the cream to one area and a placebo cream to another for 12 weeks. The goal was to see if the sirolimus cream improves the appearance and symptoms better than the placebo.
