We describe four women with idiopathic granulomatous mastitis, a rare benign disease. Age range was 32-40 years. Disease duration was less than 1 year in three patients and long term in the fourth. The diagnosis was based on histological findings, after extensive work-up ruled out malignancy and known causes of granulomatous mastitis. Treatment with prednisone with gradual tapering yielded a good response. Clinicians should consider the possibility of idiopathic granulomatous mastitis in young women with inflammatory breast processes and negative findings on relevant biopsy, laboratory, and imaging studies. Glucocorticoids are the treatment of choice; surgery is not recommended. Some patients require a glucocorticoid-sparing drug.
