title: Metastatic breast cancer masquerading as sarcoidosis.
abstract: Malignancies can cause mediastinal and hilar lymphadenopathy that is easily mistaken for sarcoidosis. We report a patient with breast cancer who initially had respiratory symptoms and thoracic lymphadenopathy. Despite the rarity of breast cancer manifesting in this way, the importance of obtaining histologic confirmation of suspected sarcoidosis is stressed.
