In the largest sarcoidosis and breast cancer case series published, to our knowledge, to date, sarcoidosis mainly occurs shortly after breast cancer diagnosis and treatment, with the classical disease features of chest involvement, but at a significantly older age, as compared to our sarcoidosis sine breast cancer patients. Our study does not allow conclusions on a possible association between two diseases, whereas large epidemiological registry-based studies yield contradictory results on the association of sarcoidosis with malignancies. Another limitation of our study is the lack of data on chemotherapy regimens administered in these patients. Last, our data are over 10 years old. In the advent of EBUS-TBNA and recently published studies on two diseases association, we believe our data may be of use for the clinicians involved in the diagnosis and management of sarcoidosis and breast cancer.
