Breast lumps: a rare site for rheumatoid nodules

BMJ Case Rep. 2015 Apr 22;2015:bcr2014208586. doi: 10.1136/bcr-2014-208586.


Granulomatous mastitis (GM) of the breast is a rare benign inflammatory disease and its presentation closely mimics breast cancer. Its diagnosis is mainly based on histology and there is no consensus agreement regarding its management. We report a case of a 60-year-old woman presenting with a right breast lump associated with a history of rheumatoid arthritis and raised rheumatoid factor. Following triple assessment (history and examination, imaging and biopsy), GM was diagnosed and she was treated conservatively.
