OBJECTIVE: Idiopathic granulomatous mastitis (IGM) is a rare, benign, chronic inflammatory breast disease with an unknown etiology. IGM patients may develop painful or painless masses, palpable lymph nodes, and skin findings that can mimic breast cancer, including retractions, skin edema, ulceration, and fistula formation. This presents a significant diagnostic challenge in clinical practice. The present study aimed to assess the early outcomes of triamcinolone acetonide treatment in patients with idiopathic granulomatous mastitis.

PATIENTS AND METHODS: After obtaining the necessary approvals from the ethics committee, patients who were admitted to the breast endocrine department of the general surgery clinic of our hospital between 2014 and 2022 with complaints of a mass, discharge, and fistula formation and who were histopathologically diagnosed with granulomatous mastitis after radiological examination by tru-cut biopsy were prospectively enrolled in the study.

RESULTS: Among the 136 patients with granulomatous mastitis, the mean age was 30.09±4.14 years, the symptom duration averaged 3 weeks (range: 1-5), the follow-up period extended for 20 weeks (range: 3-72), and the mean recurrence duration was 1.08±0.28 months. Complaints included discharge (52.2%), mass (51.5%), redness (45.6%), and pain (27.2%). Masses were predominantly on the left side (61.0%) compared to the right side (38.0%).

CONCLUSIONS: In conclusion, the heterogeneous phenotype of IGM and the lack of randomized controlled trials pose challenges. Long-acting triamcinolone acetonide proves effective in managing IGM by resolving the inflammatory process and the disease itself. Its low side effects and ease of use make it a valuable treatment modality.
