Idiopathic granulomatous mastitis: A case report

© 2013, Oncology Institute of Vojvodina, Sremska Kamenica INTRODUCTION Idiopathic granulomatosus mastitis (IGM) or lobular mastitis is a chronic breast lesion that can clinically and radiologically mimic breast carcinoma and breast abscess (1-10). The definitive diagnosis of IGM can be proved only by histopathology (HP) analysis (1-10). The majority of patients are women with the history of pregnancy and lactation. IGM can be located in any quadrant of the breast except subareolar region (3). Axillary lymph nodes are not involved. IGM can cause nipple retraction or peau d’orange, which also occurs in breast cancer. Etiology of IGM is unknown, although multiple causes have been suggested (tuberculosis, sarcoidosis, foreign body reaction, mycotic or parasitic infection) (1-8). IGM has high recurrence rate (16% to 50%) (2). In this article, we presented a case of IGM and reviewed the etiology, clinical presentation, diagnosis, and treatment of this breast disorder.
