title: A Rare Case of Oestrogen Dermatitis.
abstract: BACKGROUND
  Oestrogen dermatitis is a rare disorder characterised by cyclical eruptions in association with a woman's menstrual cycle.
  
  
  METHODS
  A 43-year-old woman with an 8-year history of cyclical inguinal dermatitis, with a negative patch test, was tested with intradermal progesterone and oestrogen.
  
  
  RESULTS
  Intradermal testing was positive for oestrogen only.
  
  
  CONCLUSIONS
  In a female patient with cyclical dermatitis, it is important to consider oestrogen or progesterone dermatitis in the differential diagnosis.
