In a pediatric population, telangiectases at sites not included as “characteristic” by the Curaçao diagnostic criteria were common, a recent study found. Therefore, the Curaçao criteria, in regard to both number and location of telangiectases, may be inadequate in the pediatric hereditary hemorrhagic telangiectasia (HHT) population. A retrospective chart review using a standardized data collection form for site and number of telangiectases was performed for pediatric patients with HHT (age, 0-18 years) from 2005 to 2016. Researchers found:
- Of 90 pediatric patients with HHT, 71% had ≥1 telangiectases.
- Of all the telangiectases counted (n=319), cutaneous telangiectases were more common (73%) than oral telangiectases (27%).
- The hands were the most frequent site, accounting for 33% of all telangiectases.
- Adolescents were more likely than children to have cutaneous telangiectases (85% vs 50%).
- The most frequent sites in children aged <10 years were the hands excluding the fingers (27%), fingers (25%), and face (23%).
- Only 23% of subjects (21 of 90) presented with multiple (≥3) telangiectases at locations considered characteristic for the current consensus diagnosis guidelines (lips, oral cavity, and fingers).
