Introduction.

Chronic granulomatous mastitis is a rare inflammatory disease with a higher incidence in females. Its symptoms and its clinical presentation cause great anxiety both in the patient and in the medical personnel, due to its behavior similar to that of malignant breast disease. There is no clear etiology or defined therapeutic management. The objective of this study was to determine the clinical-pathological characteristics, treatment and evolution of the patients with granulomatous mastitis, during the study period.

Methods.

Retrospective study in which the medical records of patients with diagnosis and management of unspecified inflammatory disorder of the breast (N61X) were reviewed, between January 2010 and December 2019. Two-hundred-thirty-six patients were found, 176 were excluded for not complying with the diagnosis of chronic granulomatous mastitis or for not having an adequate follow-up. The sociodemographic, clinical and evolution characteristics were evaluated, comparing the response obtained with each treatment.

Results.

Sixty female patients who presented varied manifestations were included, of which 38.3% (n=23) received antibiotic treatment, 30% (n=18) were treated with steroids, 8.3% (n=5) received antibiotics plus steroids, expectant management was performed in 16, 6% (n = 10), and 6.6% (n=4) of the patients were taken to surgery.

Discussion.

The best response and the lowest recurrence rate were found in patients who were observed and in those who received steroids.
