  		Figure 1a.  Craniocaudal (a) and mediolateral oblique (b) mammograms of the left breast show a lobulated lesion in the upper half of the breast (arrows), with a diffuse hazy extension toward the nipple. Note the round to oval structures in the retroareolar region (arrowheads).

  		Figure 2a.  (a) US image of the left breast shows an extensive, diffuse, and heterogeneous region with a more oval lesion in the subcutaneous fat. (b) US image reveals extension of the more solid part of the lesion into the subcutaneous fat with obvious acoustic shadowing. (c) US image demonstrates one of the oval lesions in the retroareolar region and its acoustic enhancement, a finding that indicates a more cystic nature.

  		Figure 3a.  Specimen radiograph (a) shows the extensive lesion (arrows), with the round to oval structures in the retroareolar region (arrowheads). These findings correlate with the regions of hemorrhage seen in the gross specimen (arrowheads) in b.

  		Figure 4a.  (a) Photomicrograph (original magnification, x200; hematoxylin-eosin stain) shows clusters of tumor cells with polymorphic nuclei (arrows) and crevicelike lumina filled with blood cells and lined by the defective cells (a smaller one is outlined by arrowheads). (b) Photomicrograph (original magnification, x200; CD31) shows a strong positive reaction to CD31 (brownish cells), with obvious polymorphic nuclei (arrows).
