Abstract
Background: Idiopathic Granulomatous Mastitis (IGM) is a chronic inflammatory disease of the breast. Although most of the studies have reported IGM as a rare disease, recent studies have shown an increase in the prevalence, especially in developing countries. The most important challenge is about the appropriate treatment of this disease that is not established yet. The aim of this cross-sectional study was to review the definite cases of IGM in terms of clinical characteristics and the result of treatment at Motamed Cancer Institute (MCI).
