Introduction: The idiopathic lobular granulomatous mastitis (ILGM) is a rare chronic inflammatory disease, benign and self-limited, whose etiology is unknown. The incidence remains uncertain, usually affects women of childbearing age with a recent history of pregnancy and lactation. Case report: A 37-year-old, white woman reported nodularity in the right breast associated with pain for three months. She used antibiotic for thirty days without improvement. Fever or local trauma was not nursing. On examination, there was hardened and irregular area with approximately 11.0x12.0 cm in the upper inner quadrant. At ultrasound (US), breast had several collections in the upper inner quadrant and periareolar. The lesion was biopsied and drained. The pathology was compatible with ILGM with abscess. Conclusion: ILGM is an inflammatory condition that can mimic cancer and breast abscess. The findings of physical examination and radiological findings are nonspecific. Histopathology confirms the diagnosis in the presence of noncaseating granuloma in lobular units. Given the tendency to recurrence and slow recovery, extended follow-up is essential.
