A. Axial T2-weighted image (TR/TE, 4100/90 ms) showing ill-demarcated, flattened, cutaneous lesion (arrow) with superficial ulcer formation (arrowhead) and protrusion into subcutaneous tissue. B. Axial fat-suppressed T2-weighted image (TR/TE, 3636/90 ms) showing peritumoral fat stranding (arrowheads) adjacent to cutaneous lesion (arrow); T2-hyperintense foci are not seen. C. Coronal fat-suppressed T2-weighted image (TR/TE, 4542/90 ms) clearly showing peritumoral fat stranding (arrowheads) adjacent to cutaneous lesion (arrow). D. Histological specimen (H&E stain, × 2.5) shows ill-demarcated mass infiltrating subcutaneous fat tissue.
