Abstract: Clinical reports of plasma cell mastitis complicated with breast cancer are rare. In this paper, we present a case of plasma cell mastitis complicated with ductal carcinoma in situ. The clinical imaging and pathological data were comprehensive. By reviewing the medical history, treatment history and clinical outcome, combined with previous reports in the literature, this paper discusses the clinical experience to improve the accuracy of preoperative diagnosis in such patients. This article also provides options for surgical treatment with the aim of providing additional survival benefit to the patient.
