A very aggressive form of facial hemangioma

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.

Cutaneous and leptomeningeal hemangiomas with impressive benign evolution

We describe an infant with cutaneous and leptomeningeal diffuse hemangiomata. Clinical facial anomalies were evident at birth. Routine transfontanellar ultrasonography revealed very diffuse leptomeningeal hemangioma. Magnetic resonance imaging during the first days of age confirmed vascular lesions. The patient was otherwise normal, and was monitored at ages 3.5, 9, and 18 months. Rapid resolution of the hemangioma occurred within 1 year. The infant did not present with persistent embryonic arteries, a posterior fossa, or other malformations typically reported in Pascual-Castroviejo type II syndrome. However, the characteristic skin color, leptomeningeal hemangioma, and rapid involution prompted the diagnosis of Pascual-Castroviejo II syndrome in its wider, benign spectrum.

Infantile haemangiomas: a challenge in paediatric dermatology

Infantile haemangiomas, common benign vascular tumours of childhood, are characterized by rapid growth during the first year of life and a slow regression that is usually completed at 7-10 years of age. These tumours are composed of endothelial cells with high mitotic rates and stromal components such as fibroblasts, mast cells and pericytes. Haemangiomas become a challenge when they are part of a syndrome, are located in certain areas of the body or when complications develop. The above-mentioned factors also influence the treatment modality used. However, although there remain many uncertainties regarding management, the beta-adrenergic receptor blocker propranolol is a promising new candidate for first-line systemic therapy. It produces such a dramatic and rapid response that the appearance of an infantile haemangioma should impart expeditious consideration of the risks and benefits of its use.

A patient with PHACE syndrome with marked ipsilateral cerebral atrophy

The association of posterior fossa malformation, facial cavernous hemangioma, arterial anomalies, coarctation of the aorta/cardiac defects and eye abnormalities (PHACE syndrome) represents a rare congenital anomaly with a broad spectrum of clinical manifestations and female predominance. We herein report on a girl who manifested the typical clinical features of PHACE syndrome, unusually associated with severe ipsilateral cerebral atrophy and hemiplegia. She received surgical aortoplasty, local steroid injection and laser therapy for the hemangioma, and intense physical therapy soon after diagnosis. The etiology of PHACE syndrome remains unclear, and its clinical spectrum is broad. The current case suggests that the spectrum of PHACE syndrome should be further expanded to include other forms of cerebral disorder.

The many faces of PHACE syndrome

OBJECTIVES

PHACE is an acronym coined to describe a neurocutaneous syndrome encompassing the following features: posterior fossa brain malformations, large facial hemangiomas, arterial anomalies, cardiac anomalies and aortic coarctation, and eye abnormalities. We evaluated the spectrum of disease and significance of potential underlying brain anomalies among affected children.

STUDY DESIGN

The records of 14 patients with PHACE syndrome, evaluated between 1995 and 2000, were retrospectively reviewed. A literature review revealed 116 additional cases.

RESULTS

PHACE syndrome represents a spectrum of anomalies, because most affected children have only one extracutaneous manifestation. The syndrome is associated with a high incidence of arterial and structural central nervous system anomalies with secondary neurologic sequelae. The potential for progressive neurovascular disease also exists among those patients with anomalous vasculature.

CONCLUSION

PHACE syndrome should be considered in any infant presenting with a large, segmental, plaque-type facial hemangioma. Children at risk should receive careful ophthalmologic, cardiac, and neurologic assessment.

Marked female predilection in some syndromes associated with facial hemangiomas

Analysis of the literature yielded 42 examples of the combination of sternal non-union and supraumbilical raphé without evidence of sex predilection. However, among an additional 31 cases in which the triad included facial hemangioma, there was almost exclusive female occurrence. Another condition involves extensive unilateral hemangioma of the face, absence of ipsilateral carotid and vertebral vessels, mental retardation, and Dandy-Walker malformation. Still another disorder has been proposed which includes facial hemangioma and dilatation of the carotid syphon. Both of these conditions exhibit marked female predilection. Examples of overlap of all three "disorders" cause the authors to question the independence of these disorders, hypothesizing instead that they represent a spectrum.

Association of facial hemangiomas with Dandy-Walker and other posterior fossa malformations

Cutaneous hemangiomas are common benign tumors of infancy that only rarely are associated with malformations in other tissues or organs. We report nine infants with large facial hemangiomas who also had Dandy-Walker malformations or similar posterior fossa abnormalities. On the basis of the experience with our patients and with those previously reported, we recommend radiographic imaging studies of the brain of infants with large, aggressive facial hemangiomas to rule out posterior fossa defects.
