Case Discussion
According to Pluguez-Turull et al, idiopathic granulomatous mastitis is a rare benign inflammatory breast entity characterized by lobulocentric granulomas.
It usually has a recurrent or prolonged natural disease course, usually affects parous premenopausal women, and frequently is clinically associated with hyperprolactinemia.
Ultrasound shows a large irregular hypoechoic parallel mass with tubular extensions.
The main differential diagnoses for iiopathic granulomatous mastitis is malignancy, the most important is inflammatory breast cancer. Ultrasound-guided needle aspiration may be helpful initially for distinguishing an inflammatory breast process from a malignancy.
In this case, an incisional biopsy was performed with the result of chronic granulomatous mastitis.
