Pathology: desmoplastic fibroblastoma
Desmoplastic fibroblastoma
Lobulated; hypocellular; evenly distributed "smudged" stellate-spindle cells
Eosinophilic cytoplasm with delicate tapering processes
Hyperchromatic ovoid nuclei with occasional binucleation and minimal atypia; inconspicuous mitotic activity
Prominent collagenous stroma
