(a) Mediolateral view of the left breast shows an 8 mm well-defined ovoid mass in the left upper outer quadrant (arrow). The mass (arrow) has increased in size when compared to previous mammogram. (b) The mass (arrow) as seen on the previous years mammogram. (c) There is a skin marker overlying the mass (arrow) on the craniocaudal view.

The benign appearing mass had increased in size compared to the screening mammogram one year prior (Figure 1).
Ultrasound with a 17 MHZ linear probe. (a) demonstrates a 7 mm well-defined, complex hypoechoic mass within the breast superficially, abutting the skin (white arrows). (b) The mass shows significant central vascularity.

Sonography demonstrated an 8 mm well-defined, vascular, complex hypoechoic mass within the breast superficially abutting the skin (Figure 2).
Histological examination. (a) shows an encapsulated mass consisting of monomorphic spindle cells with pointed basophilic nuclei (Antoni A tissue), set in a variable collagenous stroma (low power). Given limited excision of the encapsulated mass, adjacent normal breast parenchyma is not visualized. (b) shows areas of cells with parallel arrays of nuclear palisading known as Verocay bodies (high power).

Given limited excision of the encapsulated mass, adjacent normal breast parenchyma is not visualized (Figure 3(a)). On high power, areas of cells with parallel arrays of nuclear palisading known as Verocay bodies were noted (Figure 3(b)).
