How to diagnose Diabetic mastopathy ?
How is diabetic mastopathy diagnosed? The diagnosis of diabetic mastopathy should be considered in patients with long-standing insulin-dependent diabetes and a firm, mobile breast mass. Initial imaging may include mammography and ultrasound. While these methods can help to further differentiate the mass, they cannot provide a specific diagnosis of diabetic mastopathy with confident exclusion of malignancy. Magnetic resonance imaging (MRI) is unlikely to add additional information. Current practice dictates that a core biopsy (utilizing a needle to remove a small cylinder of tissue) be performed for a definitive diagnosis.  Biopsy results demonstrate lymphocytic lobulitis and ductitis, glandular atrophy (wasting), perivascular inflammation (vasculitis), dense keloid fibrosis (scarring), and epithelioid fibroblasts.
