Synchronous unilateral male breast cancer presenting with ipslateral gynecomastia: A triple assessment approach

Male breast cancer is rare. It accounts for less than 1% of all cancers in men and less than 1% of all breast cancers. We present the case of a 73-years-old male patient with the coexistence of ipsilateral gynecomastia and two synchronous unilateral primary malignant tumors: invasive papillary carcinoma and invasive ductal carcinoma. Our case emphasizes the rare incidence of ipsilateral synchronous unilateral primary malignant tumors and gynecomastia in male breast. Since the triple radiological assessment (clinical, mammography or ultrasonography, and core biopsy) represents a mainstay of the clinical management, radiologists should be aware of the typical findings on clinical examination, mammography and ultrasound.
