ABSTRACT

Objective:

Idiopathic granulomatous mastitis is a rare benign chronic disease of the breast. In this study, we aimed to present our treatment experience in cases diagnosed with idiopathic granulomatous mastitis.

Materials and Methods:

13 treated cases of idiopathic granulomatous mastitis, diagnosed as a result of histopathological examination, were investigated retrospectively from January 2009 to December 2012.

Results:

13 patients were included in the study. Ultrasound was performed on all patients, mammography was performed in three patient and magnetic resonance imaging was performed in two patient. For the histopathological evaluation; Tru-cut biopsy was performed in 6 patients, fine-needle aspiration biopsy was performed in 2 patients, incisional biopsy was performed in one patient and, after abscess drainage, wall biopsy was performed in 4 patients presenting with a breast abscess. Recurrence occurred in 2 patients after six months of prednisolone treatment (15.3%). Simple mastectomy was performed in these patients. During one session Latissimus dorsi flap reconstruction was performed in one patient and silicone prosthesis reconstruction in the other one. There was no recurrence observed in the two-year follow-up. Simple mastectomy was performed in 1 patient with a common fistula formation of breast.

Conclusion:

We considered that a conservative approach to idiopathic granulomatous mastitis is an appropriate treatment option. We felt that the most important factor in the response to treatment and prognosis of the disease is the severity of the disease at the time of treatment.
