The largest excised mass consisted of granulation tissue measuring 10× 6 mm. E) Microscopically, the specimen contained chronic inflammatory cells with fibrohistiocytic proliferation surrounded by amorphous collagenous material (H&E stain, ×100, ×400 with magnification). Histiocytes were positive for CD68 (×100, ×400 with magnification).
