Clinicopathological features of superficial CD34-positive fibroblastic tumor

Figure 2 Histological features of the tumor stained with hematoxylin and eosin. A: Relatively monomorphic spindled cells growing in intersecting fascicles (magnification, × 100); B: Infiltrating into the surrounding fibroadipose tissue focally (magnification, × 100); C: Epithelioid cells in the local area arranged in sheets and nests(magnification, × 400); D-F: A few scattered tumors cells exhibited irregularly hyperchromatic, bizarre, and pleomorphic nuclei with frequent intranuclear pseudoinclusions (black arrows) and rare mitotic figures(magnification, × 400); G: In some areas, tumor morphology was similar to that of inflammatory myofibroblastoma (magnification, × 100); H: In other areas, tumor morphology was similar to that of myxoinflammatory fibroblastosarcoma (magnification, × 400).
