Coexistence of Granulomas and Metastatic Breast Carcinoma Deposit in an Axillary Lymph Node A Rare Cytological Finding

Granulomatous reaction in malignancy, both intratumoral as well as in the draining lymph nodes have been reported in the literature. The main causes of granulomatous response in such cases include foreign body reaction to the necrotic tumor, therapy related granulomas or a coexistent systemic illness like tuberculosis and sarcoidosis. 3 However, in many cases a definitive cause is not found and the etiology remains obscure. We present here a case of invasive ductal carcinoma of the breast with metastatic deposit and granulomatous reaction in the ipsilateral axillary lymph node.
