Supplementary Material for: Double Trouble: Synchronous small cell carcinoma and adenocarcinoma of the pancreas- case report

Simultaneous presentation of primary tumors involving one isolated organ is few and far between. Pancreatic small cell carcinoma is unique, and it is rare to have both adenocarcinoma and small cell carcinoma present in unison within the pancreas. Presented is a 61-year-old male who was found to have synchronous small cell carcinoma and adenocarcinoma of the pancreas confirmed by endoscopic ultrasound-guided fine needle biopsy (EUS-FNB). This case stands as a reminder that synchronous pancreatic cancer is a rarity and possibility of multiple primary malignant tumors of different origin ought to be considered when multiple tumors are present within the pancreas.
