Diabetic mastopathy in an elderly woman misdiagnosed as breast cancer: A case report and review of the literature

Diabetic mastopathy: about two cases

Diabetic mastopathy is a rare and benign pathology affecting young individuals with type 1 diabetes or autoimmune diseases. It clinically resembles breast cancer, necessitating a histological examination for a definitive diagnosis. These cases underscore the diagnostic challenges and the importance of histological examination. This report details two cases of diabetic mastopathy at Mohammed VI Hospital in Marrakech. The first case involved a 35-year-old with type 1 diabetes and mastodynia, revealing a 4 x 3 cm nodule in the left breast. Biopsies confirmed fibrous breast tissue with lymphocytic infiltrates, characteristic of diabetic mastopathy, with no recurrence during follow-up. The second case featured a 38-year-old with trisomy 21 and type 1 diabetes presenting with a right breast abscess. Drainage revealed lymphocytic infiltrates, confirming diabetic mastopathy. Though diagnostically challenging, diabetic mastopathy lacks a direct link to breast cancer. Long-term cancer risks in affected patients mirror the general population.

Diabetic Mastopathy With an Associated History of Elevated Thyroid Peroxidase (TPO) and Antimitochondrial Antibodies (AMA)

Diabetic mastopathy is an uncommon, benign breast lesion that is typically seen in patients with type 1 diabetes mellitus (T1DM). The main differential diagnosis for diabetic mastopathy is breast carcinoma, which appears similarly on clinical examination and diagnostic imaging. Although the etiology of diabetic mastopathy is poorly understood, it has been associated with several autoimmune conditions, such as Hashimoto's thyroiditis, systemic lupus erythematosus, and Sjogren's syndrome. Here, we report a case of diabetic mastopathy in a T1DM patient with an associated history of elevated thyroid peroxidase (TPO) and antimitochondrial antibody (AMA) levels, giving further support to the theory of autoimmune etiopathogenesis.

Diabetic Mastopathy. Review of Diagnostic Methods and Therapeutic Options

Diabetic mastopathy is a rare breast condition that may occur in insulin-treated men and women of any age. The etiology is still unclear; however, the autoimmunological background of the disease is highly suspected. The changes in diabetic mastopathy may mimic breast cancer; therefore, its diagnostic process is demanding, and treatment options are not clear and limited. Lesions in DM are usually multiple; therefore, surgical removal is not fully effective. A well-done anamnesis with core-needle biopsy is essential and definitive in most cases. In this review, we summarize up-to-date knowledge of diagnostic methods and therapeutic options for diabetic mastopathy treatment and present three cases of diabetic mastopathy-type lesions in ultrasound and radiological examinations.
