Granulomatous mastitis: about 2 clinical cases in the mastology unit of the Hospital de Clinicas, Uruguay

Introduction: Granulomatous mastitis is a benign inflammatory disease of the breast, first described in 1972.It is a low incidence disease that occurs more frequently in premenopausal women.Its clinical presentation is nonspecific and can be confused with other more frequent clinical entities.Objectives: The aim of the present work is to report two clinical cases of a rare entity, providing an update on the subject. Clinical case:Female patient consulted for painful breast lump with flushing, local heat and fever.With a clinical diagnosis of mastitis, antibiotic treatment and drainage of seropurulent material was started and cultured, without microbiological development.Given the poor evolution, a CORE biopsy was requested and confirmed granulomatous mastitis.Discussion and conclusion: Granulomatous mastitis is a benign breast disease with a nonspecific clinical and imaging presentation.High suspicion of this pathology is essential in patients diagnosed with mastitis or recurrent breast abscesses with poor evolution under antibiotic treatment.A biopsy is essential in these patients to confirm the diagnosis and to rule out other more frequent and potentially serious pathologies such as breast cancer.
