Granulomatous mastitis: case report and review of literature.

A 38-year-old woman presented with a 5-month history of a right breast mass after delivery of her second child. The lesion simulated the picture of a carcinoma on clinical grounds. Fine-needle aspiration also reported an erroneous diagnosis of malignancy. At surgery, a discrete granuloma with microabscesses was seen without any causative organisms being identified. Open biopsy or Tru-Cut needle biopsy is recommended to prevent such an error which may result in unnecessary radical surgery.
