Thyroid poorly differentiated carcinoma metastatic to pancreas diagnosed by fine‐needle aspiration and demonstrating a novel BRAF fusion

Differentiating pancreatic duct adenocarcinoma from metastasis can be challenging by morphology alone. Metastasis from a classic papillary thyroid carcinoma can present as a poorly differentiated carcinoma and mimic pancreatic ductal adenocarcinoma's morphology. The authors did not receive any funding for the study. The data that support the findings of this study are available from the corresponding author upon reasonable request.
