Idiopathic granulomatous mastitis (IGM) is a chronic benign inflammatory breast disease that can mimic breast cancer. It is often rarer in older women and poses a problem in diagnosing an inflammatory breast tumor. We report the case of a 77-year-old patient who consulted for the management of an inflammatory breast in whom the examination found an afebrile patient with a left breast with a smooth irregular edematous and painless mass measuring 6 cm topped by fistulation crusts releasing pus under pressure with mobile ipsilateral axillary lymphadenopathy of 1 cm. The remainder of the physical examination was unremarkable. A mammogram plus breast ultrasound were carried out followed by a biopsy which came back in favor of granulomatous mastitis with foci of necrosis to investigate possible tuberculosis which was completed by immunohistochemistry came back in favor of acute granulomatous mastitis. Corticosteroid therapy combined with antibiotic therapy was started with complete regression of the symptoms after three months.
