title: Phenotypic expression of Hashimoto's thyroiditis is absolutely atypical in girls with Turner syndrome.
abstract: It is unknown whether phenotypic expression of Hashimoto's thyroiditis (HT) might be conditioned by the association with Turner syndrome (TS).
  
  
  
  To focus on the most recent pediatric studies concerning epidemiology and biochemical course of HT in TS girls.
  
  
  
  The epidemiological peculiarities of TS-related HT in pediatric age were compared with those usually observed in non-TS girls with HT and results are summarized in Tables 1 and 2.
  
  
  
  1) phenotypical expression of HT in TS girls is significantly different from that observed in girls without TS; 2) such differences concern the epidemiological picture, the biochemical presentation modes and also the natural history from HT diagnosis onwards; 3) these peculiarities of TS-related HT are not necessarily linked with a specific karyotype.
