Article Figures & Data
Figures
- Fig 1.
A 31-year-old woman (patient 10) with DFSP of the right parietal scalp. Contrast-enhanced axial CT in soft tissue (A) and bone window (B) shows a 6.1 × 4.8-cm heterogeneously enhancing mass (A, arrow) that bulges the skin surface outward and thins underlying calvaria (B, arrow).
- Fig 2.
A 31-year-old man (patient 1) with DFSP of the parietal midline scalp. MR imaging shows a 3.5 × 1.8-cm T1-isointense, T2-hyperintense, coalescing nodular mass with marked homogeneous enhancement in the parietal midline scalp (arrows). A, Axial noncontrast T1. B, Fast spin-echo T2 with fat saturation. C, T1 postcontrast axial with fat saturation. D, T1 postcontrast coronal with fat saturation.

Photographs of 2 patients with DFSP. A, Patient 16, a 25-year-old man with a large DFSP of the scalp extending from the midline near the vertex down to the left lower parietal region with subcutaneous infiltration. B, Patient 10, a 31-year-old woman with a large DFSP of the right paramedian posterior parietal scalp.
- Fig 4.
Pathologic specimen of DFSP. A, Hematoxylin and eosin stain. Elongated spindle cells with a storiform (whorled) pattern arranged around foci of collagen or vascular spaces, radiating outward (arrows). B, CD34 stain. The specimen is positive for CD34 staining. Fat entrapment is noted with a honeycomb pattern (arrow).
