Granulomatous lobular mastitis: Clinical update and case study.

BACKGROUND
Granulomatous lobular mastitis (GM) is a rare chronic benign inflammatory breast condition. It can present a diagnostic challenge and mimic inflammatory carcinoma. It causes significant morbidity for affected patients.


OBJECTIVE
The aim of this article is to provide a clinical update and case study for general practitioners, who are usually the first to see the patient.


DISCUSSION
GM is usually idiopathic. The condition presents with a large painful lump with erythema. There is often ulceration, abscess and sinus formation. Triple assessment is needed to confirm diagnosis. GM may last for 12 months or more before healing occurs. Options for management are conservative/supportive care, oral prednisone or methotrexate, or surgical excision. At present, there is no universally accepted management strategy for GM; therefore, treatment will depend on the symptoms, extent of disease and patient preferences. Supporting the patient in coping with the long-term nature of GM and the chronic discharging lesions is essential.
