The sections shows an atypical spindle cell lesions in the deep dermis, with a storiform and fascicular pattern, marked nuclear pleomorphism and very high mitotic activity (129 mitoses / 10 HPF, field diameter 0.55 mm). The spindle cells have moderate-to-abundant partially vaculated eosinophilic-to-amphophilic cytoplasm, ellipsoid-to-ovoid nuclei with coarse, irregular chromatin and, focally, nucleoli visible with the 10x objective. Malignant multinucleated-cells are identified focally with abundant pale gray cytoplasm. Suture material and reactive foreign body giant cells are seen. | |||
