On mammograms the lesion was dense with radiolucent areas inside which were thought to be compatible with fat.

On mammograms the lesion was dense with radiolucent areas inside which were thought to be compatible with fat (Fig. 1).
On sonographic imaging the lesion had smooth contours and was hypoechogenic with large hyperechoic components in between.

On sonographic imaging the lesion had smooth contours and was hypoechogenic with large hyperechoic components in between (Fig. 2).
Cut surface of the material revealed, a yellow colored, elastic, firm mass with relatively well-defined lobulated contours.

A free surgical margin of at least 3 mms was measured (Fig. 3).
(a) The lesion is composed of two to three cell layers thick, benign mammary duct epithelium lining the slit-like spaces, and a cellular spindle cell stroma. (b) The cellular mesenchymal stromal elements protrude into cyst-like spaces in a leaf-like configuration.

On microscopic examination, the lesion is composed of two to three cell layers thick, benign mammary duct epithelium lining the slit-like spaces, and a cellular spindle cell stroma (Fig. 4a). The cellular mesenchymal stromal elements protrude into cyst-like spaces in a leaf-like configuration (Fig. 4b).
(a) Adipose tissue contained a significant number of bizarre cells; with a large cytoplasm and a lobulated nucleus. (b): These cells were evaluated as "pleomorphic lipoblasts (arrow)".

These cells were evaluated as "pleomorphic lipoblasts" (Fig. 5a-b), and the adipose tissue was diagnosed as pleomorphic liposarcoma component.
