Primary hepatic leiomyosarcoma successfully treated by transcatheter arterial chemoembolization: A case report

Figure 1 Imagining features before treatment. A: Computed tomography showed a mass with inhomogeneous density, mild delayed enhancement and central necrosis; B: Hepatic angiography demonstrated a single mass with hypervascular tumor staining and dilated feeding arteries.

Figure 2 Histological examination showed a hepatic mass that consisted of spindle-shaped cells with mitotic figures and nuclear atypia.

Figure 3 Immunohistochemical staining was positive for anti-smooth muscle actin.

Figure 4 Immunohistochemical staining was positive for desmin.

Figure 5 Imagining changes after treatment. A: Computed tomography showed significant tumor shrinkage associated with satisfactory lipiodol deposition; B: No newly emerging lesions and successful embolization of feeding arteries.
