Idiopathic Granulomatous Mastitis (IGM) is a rare and benevolent disease, except few cases were reported in men. This disease is usually seen during pregnancy or lactation period. The cause of this uncommon abrasion is unclear. It usually presents as a mass. Clinically the abrasion can simulate carcinoma. This abrasion is characterized histologically by primary lobulo centric granulomas which often contain neutrophils. Foci of necrosis may be present within the granuloma. Although the lobulo centricity of the granulomas and the presence of neutrophils should raise the likelihood of IGM, other causes of granulomatous inflammation such as infection, sarcoidosis and reaction to foreign materials should always be excluded. The aim of this study was to review the clinical presentation of IGM.
