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

Figure 1 Schematic diagram of breast masses. Three separate masses of the breast, including two solid masses in the left breast and one hard mass in the right breast, were palpable.

Figure 2 Ultrasonographic images of bilateral breasts. There is a very hypoechoic zone at the 1 o'clock position of the right breast and the left breast, about 19.2 mm × 14.7 mm × 17.1 mm and 15.9 mm × 10.5 mm × 9.5 mm in size, respectively, irregular in shape, with an unclear border. There is a hypoechoic area at the 12 o'clock area in the left breast, about 5.9 mm × 6.0 mm × 5.9 mm, irregular in shape, with an unclear boundary.

Figure 3 Axial enhanced magnetic resonance images of bilateral breasts. Cross-sectional contrast-enhanced FT1WI showed that focal and heterogeneous non-mass enhancement in the upper inner quadrant of the right breast and in the upper outer quadrant of the left breast.

Figure 4 Histopathological images (hematoxylin-eosin staining). A and B: At high and medium magnification, dense lymphocytes infiltrating around the lobules of the breast, and extensive fibrosis of the surrounding stroma were observed; C: At medium magnification, myofibroblasts presented epithelioid changes.
