IgG4-related sclerosing disease (IgG4-RD) occasionally involves breast entity, which is often difficult to distinguish from malignant tumor, as both radiologically resembles. We report a case of a breast mass diagnosed as IgG4-related mastopathy (IgG4-RM) through needle biopsy, which responded well to glucocorticoid therapy. Unnecessary excision should be avoided.
IgG4相关性硬化性疾病（IgG4-RD）偶尔会累及乳腺，由于两者在影像学上相似，所以常常难以与恶性肿瘤区分开来。我们报告一例经针吸活检诊断为IgG4相关性乳腺病（IgG4-RM）的乳腺肿块病例，该病例对糖皮质激素治疗反应良好。应避免不必要的切除。
