Objective To report a case of granulomatous polyangiitis (GPA) with breast involvement, and perform a literature review to better understand this disorder. Methods Retrospectively analyze the data of a case of GPA with breast involvement, to summarize the clinical characteristics of GPA with breast involvement by searching the database (CNKI, Wanfang Data, PubMed) and comprehensively analyze the literature results. Results A case of 53-year-old woman was admitted to the Department of Rheumatology and Immunology of the First Medical Center of Chinese PLA General Hospital because of "inflamed eyelids for 8 months, hearing loss for 6 months, breast induration for 4 months". The symptoms of mammary gland were bilateral-painful breast induration with ulceration. The patient was diagnosed with GPA by positive proteinase 3 (PR3) antibody and biopsy.After treatment with prednisone and cyclophosphamide, the patient experienced a relapse and then was treated with rituximab.By March 2021 (searching CNKI, Wanfang Data and PubMed), a total of 28 English cases of GPA with breast involvement and no Chinese case were found by searching literature. The disorder often occurs in women aged 40 to 60 (60.7%, 17/28), and the typical manifestation was unilateral breast (75.0%, 21/28) involvement. Positive PR3 antibody (69.2%, 9/13) is common. Pathological characteristics of the mammary are infiltration of lymphocyte, vasculitis and granulomatosis lesion. Conclusions The disorder of GPA with breast involvement is rare with non-specific breast symptoms. Detection of anti-neutrophil cytoplasmic antibodies and pathological examination can assist the diagnosis.
