Granulomatous mastitis（GLM）is one of the non⁃lactation mastitis. It is a benign granulomatous disease that occurs in women with a history of lactation. In recent years，the disease is becoming common in clinic，with a gradually increasing incidence. Its long course as well as recurrences has done great harms to the patient physically and psychologically. Glucocorticoid is one of the most commonly administered drugs for GLM，but there is no prescription standard clinically at present so that the dosage and course of treatment vary. Even worse，the wrong usage and dosage of glucocorticoid may not only delay the patient′s condition，but also cause many side effects. In this paper，the authors have reviewed a large number of domestic and foreign literatures on glucocorti⁃coid treatment of GLM in recent years，and elaborated the latest progress for clinical reference.
