Figures

Fig. 1
Fig. 1
An axial T1-weighted MR image shows the somewhat poorly defined mass in the dorsal subcutaneous soft tissues of the forearm, which is isointense to low in signal compared with the underlying muscle. The high signal centrally likely attributable to hemorrhage and the prominent surrounding low signal edema can be seen.
Fig. 2
Fig. 2
An axial T2-weighted MR image with fat saturation shows the heterogeneous, but predominantly high signal mass with a thin, peripheral low-signal-intensity rim and marked surrounding soft tissue edema.
Fig. 3
Fig. 3
An axial T1-weighted MR image with fat saturation after the intravenous administration of gadolinium shows heterogeneous enhancement of the mass and exuberant enhancement in the surrounding soft tissues.
Fig. 4
Fig. 4
A photomicrograph shows frequent round to polygonal tumor cells with ample light cytoplasm and well-defined cell borders (Stain, hematoxylin and eosin; original magnification, ×60).
Fig. 5
Fig. 5
Conspicuous vascular invasion by the lesion is shown (Stain, hematoxylin and eosin; original magnification, ×4).
Fig. 6
Fig. 6
Extensive lymphatic permeation by the lesion is shown (Stain, hematoxylin and eosin; original magnification, ×20).
