Diabetic mastopathy is a rare, benign breast disease that presents with fibrous breast lumps usually induced by the hyperglycemic state in diabetic patients and often associated with type 1 or 2 diabetes mellitus. Clinical and radiographic appearances are usually confusing and pathologic confirmation is essential for diagnosis mainly to rule out malignancy. However, a specialized breast pathologist often utilizes patient's history of diabetes as a guide to solve this diagnostic dilemma. We report a challenging scenario in which a case of diabetic fibrous mastopathy was pathologically identified with no previous given history of diabetes. This benign breast entity should be included in the differential diagnosis of breast lumps even without history of diabetes that may be overlooked before surgery.
