Objective:
To analyze the hormonal dependence of estrogen and progesterone receptors in endometriosis of the bladder.
Methods:

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.
