Idiopathic Granulomatous Mastitis

Objective: This study aims to retrospectively describe the clinicopathological pattern and management experience of idiopathic granulomatous mastitis in women attending care at royal hospital, a tertiary care center at sultanate of Oman. Then to compare our experience with the current literature trends. Methods: The data of patient were retrospective reviewed from 1st of January 2012 to 31st of December 2017, after receiving ethical approval from the center of studies and research. Results: Sixty-four patients were conformed to have idiopathic granulomatous mastitis. All of our patients were in the premenopausal phase with only one being nulliparous. Mastitis was the most common clinical diagnosis and half of them had a palpable mass. Most of our patient had received antibiotics during their treatment span. Drainage procedure was done in 73% of the patient, whereas excisional procedure was done for 38.7%. Only 52.4% of our patient were able to achieve complete clinical resolution within 6 months of follow-up. Conclusion: There is no standardized management algorithm, due to the paucity of high-level evidence comparing different modalities. However, Steroids, Methotrexate and surgery are all considered to be effective and acceptable treatments. Moreover, current literature tends towards multi-modality treatments planned tailed case-to-case based on the clinical context and patient’s preference.
