Figure 4 Diagnosis of metastatic retroperitoneal leiomyosarcoma. A: Strong positive SMA immunohistochemical staining in clitoral tumor (× 100); B: Immunohistochemically, spindle-shape tumour cells revealed staining for desmin in the clitoral tumor (× 100); C: Spindle shaped tumour cells with eosinophilic cytoplasm and nuclear polymorphism in retroperitoneal leimyosarcoma (× 100 magnification, Haemaetoxylin-Eosin staining); D: The retroperitoneal tumour cells were negative for desmin in retroperitoneal leiomyosarcoma (× 100); E: Immunohistochemistry reveals CD34 negative tumour cells and CD34 positive vascular endothelial cells (arrows) in retroperitoneal leiomyosarcoma (× 200).
