Objectives: This study aimed to retrospectively describe the clinicopathological pattern and management experience of idiopathic granulomatous mastitis in women receiving care at the Royal Hospital, a tertiary care centre in Oman. The study then compared the researchers’ experience with the current literature trends. Methods: The data of patients from January 2012 to December 2017 were reviewed retrospectively, after receiving ethical approval from the Centre of Studies and Research. Results: This retrospective study included 64 patients were confirmed to have idiopathic granulomatous mastitis. All patients were in the premenopausal phase, with only one being nulliparous. Mastitis was the most common clinical diagnosis; furthermore, half of the patients had a palpable mass. Most patients had received antibiotics during the span of their treatment. Drainage procedure was done in 73% of the patients, whereas excisional procedure was done for 38.7%. Only 52.4% of patients were able to achieve complete clinical resolution within six months of follow-up. Conclusion: There is no standardised 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 multimodality treatments planned tailored case-to-case based on the clinical context and patients’ preference.
