We report the first case of synchronous Paget's disease of the vulva and breast diagnosed within a period of 7 months. This is the fourth case of mammary Paget's disease associated with either preceding or following vulvar Paget's disease documented in the literature. With consideration of increasing age of the population, and the fact that vulvar Paget's disease affects elderly women and that breast cancer is the most common malignancy of women in the United States, one can anticipate the occurrence of these two conditions to be more prevalent in the future.
