A Refractory Case of Granulomatous Mastitis Treated with Methotrexate / 대한내과학회지

ABSTRACT

Granulomatous mastitis (GM) is an uncommon chronic inflammatory disease of the breast that can mimic breast carcinoma or infection. The treatment options include expectant management, complete resection, and corticosteroid therapy, although no standard treatment has been established. Recently, several case reports have suggested that methotrexate is another effective treatment for GM. Here, we describe the first Korean case of recurrent GM successfully treated with low-dose weekly methotrexate and review the relevant literature.
