title: Cutaneous mastocytosis complicating pregnancy.
abstract: BACKGROUND
  Telangiectasia macularis eruptiva perstans, a rare form of cutaneous mastocytosis associated with elevated histamine excretion, has not previously been reported to complicate pregnancy.
  
  
  METHODS
  A woman presented in the late second trimester with an anaphylactoid reaction, rash, uterine contractions, and vaginal bleeding. Skin biopsy revealed perivascular mast-cell infiltration. Her urinary histamine excretion was markedly elevated. She was treated successfully with tocolytics and antihistamines.
  
  
  CONCLUSIONS
  Elevated histamine excretion in biopsy-proven cutaneous mastocytosis may be associated with preterm labor.
