title: Tubular adenoma of the breast in a 73-year-old woman.
abstract: A 73-year-old woman presenting with a right breast mass is described. The patient underwent lumpectomy under a diagnosis of breast cancer. However, histopathologically the surgical specimen was tubular adenoma of the breast. This is a rare benign tumor that is difficult to differentiate from breast cancer clinically, especially in elderly patients. We describe two reported cases of tubular adenoma in patients older than 65-years in Japan, as well as the present case.
