A Retrospective Study of Idiopathic Granulomatous Mastitis Treatment and Outcomes.

Granulomatous mastitis (GM) is a rare, poorly characterized inflammatory disease with a broad differential diagnosis that includes both benign and malignant conditions such as infectious mastitis, sarcoidosis, and inflammatory breast cancer. The etiology of most cases is idiopathic (IGM). In this retrospective study, we present our experience of 31 patients with IGM, underscoring management and treatment outcomes.
