title: Diabetic mastopathy: case report and summary of literature.
abstract: Diabetic mastopathy is an uncommon, benign breast condition seen in type 1 and less frequently type 2 diabetic patients. It is characterized by a dense fibrous stromal proliferation of breast tissue, clinically mimicking cancerous masses, thus leading to worrisome investigations. Clinicians and pathologists must distinguish this benign condition from malignant causes because surgery may worsen the case as these lesions tend to recur more extensively at the site of resection. We present the case of a young woman with type 1 diabetes with typical diabetic mastopathy and summarize the literature to increase awareness of this troublesome but benign disorder.
