Idiopathic granulomatous mastitis is a rare, chronic, benign and inflammatory disease of the breast. Usually, since the disease presents as an irregular inflamed mass in the breast, it may be confused with breast cancer clinically and radiologically. I want to evaluate the association of breast cancer and IGM in light of the literature data. My case is a 58-year-old postmenopausal woman, who came to our clinic because of a mass in the left breast. Following a tru-cut biopsy which revealed invasive ductal breast cancer, she was operated on in June 2018. The patient developed a mass in the same breast 1.5 years later, and the tru-cut biopsy result this time was IGM. The patient was treated with an oral steroid. According to the literature, while there are many cases where IGM mimics breast cancer, there are 4 cases where IGM and breast cancer were found together. In one of two cases
where they coexisted, it was invasive breast cancer found with IGM and, in the other; it was IGM with ductal carcinoma in situ. In the other two cases, invasive breast cancer developed years after the IGM treatment. In my case, IGM developed 1.5 years after the patient was treated for invasive ductal cancer. The evidence in the available literature data, as well as my case, reveals that IGM may either exist before or after the onset of breast cancer. Therefore, it would be more correct to accept IGM as a benign breast disease.
