title: Decidual cast after discontinuation of oral contraceptives use in a young girl.
abstract: BACKGROUND
  The differential diagnosis of tissue passed per vagina in a young girl includes aborted pregnancy, rhabdomyosarcoma, polyp, and very rarely decidual cast.
  
  
  METHODS
  A 10-year-old girl using oral contraceptives for menorrhagia presented with a decidual cast after discontinuing the drug. Symptoms disappeared during clinical follow-up without any intervention.
  
  
  CONCLUSIONS
  Decidual cast formation is an unusual entity of unknown origin. It's generally seen during treatment with variable contraceptives. This is the first case described with desogestrel and it occurred after discontinuing treatment.
