case_images: A gross pathology examination of the surgically resected tumor revealed a size of 21x15.3x12 cm and a smooth and partially fibrous outer surface. An analysis of the tumor cross-section revealed encapsulated yellowish-brown nodules and widely distributed necrotic and hemorrhagic lesions (Fig. 2).
case_images: Immunohistochemical staining of the tumor. The Ki-67 index of the tumor cells is 20% (x400).
