Introduction:

Diabetic mastopathy (DM) is an uncommon, benign entity of self-limiting fibro inflammatory breast disease. It is associated with type 1 diabetes mellitus (T1DM). DM represents a collection of clinical, radiological, and histological findings on the breast

Case report 1:

We report a 37-year-old woman, with T1DM diagnosis. The chief complaint included a 2-week history of an enlarging left breast lump. BI-RADS 4c was diagnosed in mastography. Pathology study showed DM

Case report 2:

A 42-year-old woman with T1DM diagnosis noted an enlarging left breast mass. BI-RADS 4c lesion was diagnosed by mastography. DM was determined by pathology study.

Literature review:

The association between T1DM and DM has been related to microvascular complications and is clinically indistinguishable from breast cancer. Breast ultrasound is the standard of choice for DM diagnosis. Pathogenesis of DM remains unknown. As a benign disease DM does not need surgery, only surveillance has been recommended.

Conclusion:

The DM should be considered in patients with microvascular complications of T1DM.
