title: [Vesical endometriosis. Report of a case with immunohistochemical study].
abstract: OBJECTIVE
  To analyze the hormonal dependence of estrogen and progesterone receptors in endometriosis of the bladder.
  
  
  METHODS
  A case of endometriosis of the bladder that had presented as a tumor in a 30-year-old female is described. Immunohistochemical studies were performed using estrogen and progesterone antireceptor antibodies.
  
  
  RESULTS
  A strong positivity for progesterone in the endometriotic stromal cells was demonstrated. A mild positivity for estrogen in the glandular epithelial and stromal cells was observed.
  
  
  CONCLUSIONS
  The present case demonstrates the hormonal dependence of endometriosis of the bladder and raises the possibility of utilizing hormone therapy in specific patients.
