case_images: Axial image of MRI shows a large, expansive heterogeneous soft tissue mass with contrast, closely applied to the muscular structures, and infiltration and obliteration of adjacent structures (white asteriks).

case_images: Magnetic resonance imagining (MRI) demonstrated a large mass that closely approximated the muscular structures and surrounding connective tissue (Figure 1).
case_images: Gross cross-sectional view of pathologyic resected specimen. The gross lesion is poorly circumscribed and usually measures between 5 and 15 cm. On cut section, it is hard and tan-white. The lesion is poorly circumscribed and is centered in skeletal muscle and the adjacent fascia. There often are infiltration and obliteration of adjacent structures.

case_images: Macroscopic surgical margins were free from all aspects of the tumor mass (Figure 2).
case_images: Desmoid fibromatosis showing fascicular arrangement of bland fibroblasts, which are interrupted by thin-walled, compressed vascular channels resulting in an appearance akin to a hypocellular scar. Note entrapped muscle fibers. No mitotic activity or nuclear pleomorphism is present (H&E, original magnification, 40x).

case_images: Microscopic tumor margins were negative, and there was no evidence of malignant change (Figure 3).
