Abstract

An angiolipoma is a common mixed connective tissue tumor that commonly occurs in the trunk and extremities, and has been rarely reported in the breast. It is a benign variant of a lipoma that shows various appearances on mammography. It is usually seen with a well circumscribed homogeneously hyperechoic pattern on ultrasound. We report a rare case of an angiolipoma of the breast with no definite abnormality on mammography, appearing as an irregular homogeneously hyperechoic lesion on ultrasound.

  Figure 1 Image findings for a 40-yr-old woman with a palpable mass in the right breast. (A, B) Right mammograms show a heterogeneously dense breast without a focal lesion or microcalcification at the palpable site. (C) An ultrasonogram shows an indistinct irregularly shaped, homogeneously hyperechoic mass (arrows) with extension to the subcutaneous layer.

• 

  Figure 2 Microscopically, the mass consists of adult adipose tissue (arrow) and proliferating capillaries (arrowhead) in the fibrous stroma (H&E stain, ×100).
