Breast disease in sarcoidosis.
BACKGROUND
Breast disease in sarcoidosis can be classified as sarcoidosis patients with breast granulomas, sarcoidosis patients with breast cancer, and breast cancer patients displaying sarcoidosis-like breast reactions.


METHODS
We reviewed the medical records of 629 women with sarcoidosis followed in the Interstitial Lung Disease Clinic at the University of Cincinnati for findings associated with breast disease. In addition, three women with breast cancer who had granulomas in proximity to their tumors were also examined.


RESULTS
Abnormal breast examinations or mammograms were reported in 15 patients with sarcoidosis (2% of women with sarcoidosis). Breast biopsy revealed granulomas consistent with sarcoidosis in six. One of them developed breast cancer five years later. Breast cancer was identified in twelve further patients, therefore a total of thirteen patients with breast cancer were identified. Ten were diagnosed with breast cancer plus sarcoidosis: sarcoidosis preceded breast cancer in three, followed breast cancer in five, the two diseases appeared simultaneously in two. Three additional women with breast cancer were also evaluated and classified as patients with sarcoid-like reaction. Review of the mammographic and physical findings could not distinguish between sarcoidosis in the breast and breast cancer.


CONCLUSIONS
Sarcoidosis patients develop breast cancer at the expected frequency. The breast cancer diagnosis may precede or follow that of sarcoidosis. There is no relationship between stage of sarcoidosis or treatment and the development of cancer. Because physical examination and mammography findings are unable to distinguish between sarcoidosis and malignancy, biopsy of all suspicious lesions in sarcoidosis is recommended.
