Mammary involvement in a patient with sarcoidosis.

Sarcoidosis is a systemic granulomatous disease of unknown etiology. Sarcoidosis affects multiple organs; the lungs, lymphoid system, eyes and skin are usually involved. Commonly, any organ system may be affected. Sarcoid involvement in the nervous system, locomotor system, lacrimal and salivary glands, heart, kidney and liver has been recognized in patients with sarcoidosis. However, sarcoid involvement of the breast parenchyma has been extremely rare in patients with sarcoidosis. Herein, we report a patient with a sarcoid breast mass who had bilateral hilar lymphadenopathy and lymphocytosis in bronchoalveolar lavage analysis.
