Intralesional Corticosteroid Therapy in Hemangiomas: Clinical Outcome in 160 Cases
Chantharatanapiboon W 
Background: Hemangiomas, one of the most common childhood neoplasms, exhibit a characteristic history of
rapid proliferation and slow spontaneous involution. Most of hemangiomas are often managed conversatively,
requiring numerous years for spontaneous involution. However, hemangiomas can threaten function in 10%
to 20% of cases, less than 1% are truly life threatening. All these serious hemangiomas require treatment to
avoid severe sequelae and in some rare cases to save the infant’s life.
Objective: To evaluate the efficacy, side effects, and influencing factors of intralesional triamcinolone in
enhancing regression of various sizes and locations of hemangiomas and to discuss the optimal time and
interval of the treatment.
Material and Method: The retrospective study was done on 160 pediatric patients with hemangiomas, treated
with intralesional triamcinolone injection at age 1 month to 15 years by the author at Queen Sirikit National
Institute of Child Health from March 1995 to March 2008. Data were collected from interviews, examinations,
medical records, photographs and telephone conversations. Standard statistical methods were used for comparison.
The hemangioma sizes were classified into small (> 0-3 cm), medium (> 3-6 cm) and large (> 6-9 cm).
Indications for the treatment were rapidly growing lesions, lesions with visual problems, bleeding, ulceration
and cosmetic concern. Intralesional injection of triamcinolone was given in a dose of 1 to 2 mg/kg of body
weight (maximum of 60 mg). The interval between the treatments varied from 4 to 12 weeks. Most patients were
followed up at monthly interval at least 14 months through clinic visits. Mean follow-up was 3.6 years (range
14 months to 12 years).
Results: One hundred and sixty patients, 111 girls and 49 boys were treated with this technique. The mean age
at first injection was 16.1 months, with a range from 2 months to 9 years. The number of intralesional triamcinolone
injection varied from single injection to twelve injections with a mean of 5.7 injections. The overall
response rate was 90% (excellent at 70% and good at 20%). Maximum response was observed in children
below the age of 1 year (excellent at 77.8% and good at 15.7%) and parotid hemangiomas (excellent at 93.1%
and good at 6.9%). The difference between hemangiomas sizes and treatments interval result was not of
statistical significance.
Conclusion: Intralesional administration of triamcinolone was devoid of systemic side effects and an effective
initial modality for rapidly growing hemangiomas.
