title: A case of a fibroadenoma coexisting with an invasive lobular carcinoma in the breast.
abstract: A case of a fibroadenoma coexisting with an invasive lobular carcinoma of the breast in a 60-year-old female is presented, and its pathological features are correlated with high-resolution magnetic resonance imaging (HR-MRI) and other imaging findings. The patient presented with the chief complaint of having a palpable mass in her right breast for 3 months. Mammography revealed a lobular mass with a micro-lobulated margin, which suggested a malignant nature; however, it included coarse calcifications. Sonographic imaging and HR-MRI findings were compatible with malignant tumor. Cytology was performed, and the results indicated an invasive carcinoma. Breast-conserving surgery was performed as a curative operation. The pathological features revealed a fibroadenoma coexisting with an invasive lobular carcinoma. This case suggests that radiologists should always pay attention to the associated malignant imaging characteristics, such as the shape and border of the mass, whenever a mass demonstrates benign-like calcifications.
