Abstract

Spontaneous breast infarction is a very rare complication of fibroadenoma of the breast. We present an interesting case of a 33-year-old woman with spontaneous infarction of hyperplastic breast tissue related to pregnancy and lactation. Mammography showed an oval, circumscribed, fat-containing mass with microcalcifications. Ultrasonography revealed an oval, circumscribed mass with echogenic dots. Color Doppler imaging revealed presence of minimal vascularity at the periphery of the mass.

Figure

  • Fig. 1 A 33-year-old woman with spontaneous breast infarction of hyperplastic tissue. Craniocaudal mammogram of her right breast shows an oval shaped large fat-containing mass with a circumscribed margin and microcalcifications (arrow).

  • Fig. 2 Ultrasonography findings of infarcted hyperplastic breast tissue. A. On ultrasonography, the mass appears as an oval shaped structure with a circumscribed margin, and heterogeneous echogenicity with a combined pattern of posterior features. A few echogenic dots can be seen within the mass (arrows). B. Color Doppler sonogram shows only minimal vascularity at the periphery of the mass.

  • Fig. 3 Histopathology of infarcted hyperplastic breast tissue. A. Gross examination of the specimen shows a 4.8 × 3.6 × 2.3 cm, well circumscribed yellow colored mass with areas of hemorrhage, which is distinct from the surrounding breast parenchyma. B. Low-power microscopic view of the lesion shows extensive necrosis of hyperplastic breast tissue (arrows) (H&E, × 10). C. Higher power photomicrograph shows microcalcifications within the mass (arrows) (H&E, × 100). H&E = hematoxylin and eosin
