Resumen

Objective: To determine the clinical characteristics, diagnosis and treatment options of non-caseating granulomatous mastitis. Methods: The present study is descriptive, cross-sectional, retrospective and non-experimental of 61 patients treated at the Hospital Belen of Trujillo, from January 2018 to December 2022. The inclusion criterion was that they have a histopathological diagnosis of granulomatous mastitis without caseification Acid-Fast Bacilli negative. Results: 93.4% affected women of reproductive age (age average 33 ± 7 years). Parity, having finishing breastfeeding and the use of contraceptives were associated in a statistically significant way with matitis (p ≤ 0.05). It mostly affected the left breast. The tumor varied between 3 and 11 cm with an average size of 5 ± 2 cm. In 49.2%, the tumor was accompanied by one or more fistulas. 38.5% used hormonal contraceptives. The culture of 25 biopsied breast tissues was negative. The ultrasound study was categorized in 91.8% as BIRADS 2 and 3. 67.2% improved with anti-tuberculosis treatment even though there was no evidence of positive AFB. 32.8% improved with diverse treatment, with antibiotics and without antibiotics. Conclusions: This type of mastitis occurs in the reproductive stage of the woman, but after the lactation period. Hormonal contraceptives could predispose to this condition. Its management is variable, it can be done with anti-tuberculosis drugs, common antibiotics and in extreme cases surgical resection.
