Figure 4. Pathology slides of the scalp leiomyosarcoma in the presented patient. (a) Low-power field (× 10): skin with ulceration and proliferation of neoplastic smooth muscles cells occupying the dermis. (b) High-power field (× 40): neoplastic smooth muscle cells showing cytologic atypia, frequent mitosis and single cell apoptosis. (c) Medium-power field (× 20) with immunostain for desmin: the tumor is diffusely positive with desmin.
