Insights
Infantile hemangiomas (IH) can lead to complications like ulceration, especially mixed and segmental types. Recurrence is more common in females and segmental IH, requiring tailored treatment protocols for high-risk cases.
Area of Science:
- Pediatric Dermatology
- Vascular Anomalies
- Clinical Research
Background:
- Infantile hemangiomas (IH) affect 4-10% of children.
- Identifying risk factors for IH complications is crucial for effective treatment.
Purpose of the Study:
- To identify risk factors for complications, recurrence, and unaesthetic sequelae in infantile hemangiomas.
- To inform therapeutic strategies and improve patient outcomes.
Main Methods:
- Retrospective cohort study of 190 patients with infantile hemangiomas.
- Data collected from 2006-2018 at a Dermatology Service.
Main Results:
- 24% of patients experienced complications, most commonly ulceration, linked to mixed IH, segmental IH, and gluteal location.
- Recurrence occurred in 16.6% of treated patients (all female), primarily on the head/neck.
- Segmental IH and PHACES syndrome required longer propranolol treatment (mean 12.7 months).
Conclusions:
- Mixed and segmental infantile hemangiomas are significant risk factors for ulceration and sequelae.
- Female sex and segmental IH are associated with higher recurrence rates.
- Specific treatment protocols are needed for infantile hemangiomas with high recurrence risk.
Background:
Infantile hemangiomas (IH) occur in approximately 4% to 10% of the pediatric population. The identification of clinical subtypes and conditions that indicate increased risk for complications is essential for therapeutic success.
Objectives:
To identify risk factors for complications, recurrence and unaesthetic sequelae.
Methods:
Retrospective cohort of patients with infantile hemangiomas undergoing follow-up at the Dermatology Service of Universidade Federal de Ciências da Saúde de Porto Alegre, between 2006 and 2018.
Results:
190 patients were included; 24% had some type of complication, ulceration being the most frequent, and 86% required treatment. On correlation, ulceration was statistically related to mixed IH (p = 0.004), segmental IH (p < 0.01) and location in the gluteal region (p = 0.001). The mean time of treatment with propranolol was 12.7 months. Patients with PHACES syndrome and segmental infantile hemangioma required longer treatment (p < 0.001 and p = 0.0407, respectively), as well as those who started treatment after five months of life (p < 0.0001). Recurrence occurred in 16.6% of the treated patients, all-female; 94% were located on the head and neck (mainly on the upper eyelid, cyrano, S3 segment, and with parotid involvement); 61% and 38.8% were of the mixed and deep subtypes, respectively. Approximately 1/3 of the patients had some unaesthetic sequelae.
Study Limitations:
As this is a retrospective study, data and photos of some patients were lost.
Conclusions:
Mixed and segmental hemangiomas are risk factors for ulceration and sequelae. Recurrence occurs more often in females and segmental hemangiomas. Segmental infantile hemangioma and PHACES syndrome require a longer time of treatment. Specific protocols are required for infantile hemangiomas with a high risk of recurrence.
