case_images: Leiomyosarcoma arising from the intrapancreatic common bile duct. The tumor infiltrates the full thickness of the common bile duct, extends into its lumen and invades the pancreas. Tumor cell necrosis, high cellularity, many mitotic counts, pleomorphism, and nuclear atypia are present in the neoplasm (H&E, x10).
