(A) Sheets of solidly packed, spindle-shaped cells arranged in bundles and fascicles, imparting a herringbone appearance, with several mitotic figures and vascular rich pattern. (B) MRI of the right forearm (right image) and right hand (left image); coronal STIR images showing a 6x2x1.5 cm high signal intensity mass involving the flexor digitorum profundus muscle and extending to the flexor digitorum superficialis muscle. Similar infiltrative mass is extending between the metacarpal bones and involving the interosseous muscles. Both the ventral and dorsal aspects of the hand were involved. (C) Follow-up MRI of the hand and forearm after end of therapy. Coronal STIR images showing normal signal intensity of the soft tissues with no evidence of recurrent or residual tumor. (D) CT scan of the left arm with IV contrast administration. Large heterogeneously enhancing soft tissue mass measuring 8x3 cm and showing areas of enhancement and necrosis.

CT scan revealed an 8.3x5x2.7 cm, highly vascularized mass over the medial aspect of the left arm, with areas of necrosis (Figure 1D).
