Macroscopic findings of the resected specimen and distribution of the carcinomatous and sarcomatous components. a The lesion consisted of two components: a 7.5-cm type 2 tumor and a 9-cm type 1 tumor at the proximal end of the type 2 tumor. We also observed a 6-cm mass of tumor tissue that appeared to be separate from the type 1 tumor. b The type 2 tumor showed a white-gray cut surface, while the type 1 tumor showed the same white-gray cut surface with necrosis and hemorrhaging. The blue areas indicate the carcinomatous component, and the red area shows the carcinomatous with sarcomatous components
