A 35-year-old woman presented to the surgery outpatient department with a lump in her right breast for 2 months and pain for 1 month. After clinical examination and relevant investigations, we kept a working diagnosis of antibioma. The lump was excised under local anaesthesia and biopsy was sent. However, histopathological examination reported multiple non-caseating granulomas without acid-fast bacilli. Two months later, she developed a sinus with serous discharge at the scar site. At the same time, she developed pain in the left upper breast, which subsequently progressed to an abscess. Incision and drainage of the abscess was done, but the wound did not heal, and a discharging sinus appeared at the site. Finally, a diagnosis of idiopathic granulomatous mastitis was made, after excluding all other causes, and the patient was prescribed oral steroids. She recovered fully after 8 months and there is no recurrence till date.
