Abstract

Idiopathic granulomatous mastitis (IGM) is a rare, chronic inflammatory condition of the breast, which is challenging to diagnose and manage due to its clinical resemblance to acute mastitis or abscesses. The condition is most commonly seen in women of reproductive age, often during the postpartum period or lactation, though it may also affect non-lactating women. We present a case of a 29-year-old pregnant female who presented with a painful mass in her left breast, which initially mimicked acute mastitis but later turned out to be idiopathic granulomatous mastitis. The diagnosis was confirmed by biopsy after multiple treatments for presumed acute mastitis failed. The case highlights the complexity of diagnosing and managing IGM, particularly in pregnant patients, and emphasizes the need for a multidisciplinary approach.
