Granulomatous Mastitis With Breast Abscess Caused by Salmonella

Granulomatous mastitis (GM) is a rare disease that occurs in young premenopausal women, is mostly idiopathic, and is less likely to be caused by infection and trauma. It is also strongly associated with pregnancy, lactation, and hyperprolactinemia. GM superimposed by infection with abscess formation caused by Salmonella is extremely rare. Upon reviewing the literature, our case is considered to be the first reported case globally. Most breast abscesses are caused by Staphylococcus aureus.
