An extremely rare case of pancreatic metastasis of esophageal squamous cell carcinoma

Figure 1 Enhanced computed tomography (A) and 18F-2-fluoro-2-deoxy-D-glucose positron-emission tomography (B) showed a tumor of the pancreatic body (arrows). The major axis of the tumor was 15 mm. Maximum standardized uptake value of the lesion was 5.49.

Figure 2 Macroscopic findings of the specimen revealed a 15 mm × 11 mm tumor in the pancreatic body (arrows).

Figure 3 Pathological examination revealed squamous cell carcinoma. A: Squamous cell carcinoma in the pancreas; B: Squamous cell carcinoma in the esophagus resected previously (hematoxylin-eosin staining, A: × 40; B: × 400); C: Vascular invasion in the pancreatic metastasis; D: Esophageal carcinoma (elastica van gieson staining, C: × 100, D: × 400).
