Abstract: Propranolol has been the first-line treatment for problematic infantile hemangioma (IH) since 2008. The recurrence of IHs after stopping treatment with propranolol was reported in several studies. Mechanisms underlying this phenomenon have not been elucidated so far. Our study is the first to show the general pathology of recurrence of IH after stopping treatment with propranolol. It can provide help for the clinical treatment of IHs.
