Propranolol for treatment of infantile hemangiomas

Propranolol: Effectiveness and Failure in Infantile Cutaneous Hemangiomas

Infantile hemangiomas (IHs) occur in early infancy and are considered to be one of the most frequent childhood tumors. Poor responsiveness to the treatment and complications are reported in about 10 % of patients. For years, the most common treatments for cutaneous and complicated IHs were corticosteroids, interferon-α, vincristine, laser therapy, or surgical intervention. More recently, treatment with propranolol has been reported with high success rates, both in the cutaneous and complicated form of IHs, and it is now considered to be the first-line treatment for IHs. Herein we report five cases of cutaneous IHs who presented at our unit between January 2011 and June 2012: in three of five patients, the lesion improved soon after the beginning of propranolol treatment; one case presented slow but complete resolution; and in one patient the treatment was unsuccessful. Patients who do not respond to propranolol have been seldom reported in the literature. However, the failure of propranolol treatment in childhood hemangiomas has been more frequent in our experience than that reported in previous case series. More attention should be given to the cases that poorly or negatively respond to treatment, and to the mechanisms underlying the failure to respond to treatment with propranolol.

Infantile Hemangioma: A Brief Review

Infantile hemangiomas as frequent infancy tumors have been a controversial issue of medical scientists worldwide. Their clinical aspects are various and their physiopathology is yet to be fully understood. Numerous publications outline the characteristics, causes, evolution possibilities and therapeutic approaches. Deciding whether to treat or not is the main question of this kind of pathology. Hemangiomas that have complications or can cause irreversible damage need therapy. This is a brief review of up-to-date information regarding the presentation of infantile hemangiomas and target-therapies.
