Bilateral involvement of IGM has been reported in a few cases. To our knowl- cancer; edge, this study is the largest series of bilateral cases to date. The goals of this study were corticosteroids; to present clinical features of bilateral IGM and to evaluate the results of treatments. granulomatous Materials and methods: We performed a retrospective review of the idiopathic granulomatous mastitis; mastitis database from 2010 to 2013. Ten female patients who met required histologic and clin- idiopathic; ical criteria of IGM in both breasts were included in study. Demographic data, clinical findings, tuberculosis medication history, and radiologic findings are presented. Results: The mean age at onset of the disease was 38.4 Æ 8.3 years (range: 29e52 years). Nine patients had no recurrence during a mean follow-up period of 21 months (range: 11e26 months). Additionally, the median time to second breast involvement was 15.6 months. Conclusion: Bilateral IGMs have a higher rate of more relapse and greater resistance to medical therapies than do unilateral IGMs. Surgical management should be avoided unless all medical treatment options have been exhausted. Nevertheless, expectant management seems a rational option for the treatment of bilateral IGM. Copyright ª 2015, Asian Surgical Association. Published by Elsevier Taiwan LLC. All rights reserved.
