Pancreatic carcinosarcoma: First literature report on computed tomography imaging

Figure 4 Histological examination of the lesion. A: Microscopy of the tumor indicated a predominance of dual disparate sarcomatous and carcinomatous components. Spindle-shaped tumor cells and well-differentiated adenocarcinoma cells coexisted and intermingled (HE staining, × 200); B: Cytokeratin 7 immunostaining showed strong and diffuse expression in the ductal adenocarcinoma cells (× 200); C: Sarcomatous cells were immunopositive for vimentin (× 200).
