Abstract
Sclerosing lymphocytic lobulitis, also known as diabetic mastopathy, is a rare and benign pathology predominantly observed in young women with type I diabetes, typically with degenerative complications. Clinically, the lesion can mimic carcinoma. Biopsy remains the gold standard for a definitive diagnosis. Radical surgery is generally unnecessary when histological verification can be achievedusing core needle biopsy. This case report details the clinical and radiological findings, as well as the management of a 33-year-old patient with a 22-year history of type I diabetes who presented with sclerosing lymphocytic lobulitis.
