title: Primary Squamous Cell Carcinoma of the Pancreas as a Cause of Biliary Obstruction.
abstract: Primary squamous cell carcinoma of the pancreas (SCCP) is a rare neoplasm, given a lack of naturally occurring squamous cells within the pancreas, accounting for only 0.2% of all pancreatic cancers. The etiology is unknown. Symptomatology is non-specific and similar to other pancreatic neoplasms. No non-invasive testing can adequately rule in SCCP, and workup should proceed similarly to any pancreatic mass. Tissue sampling is required for diagnosis and guidance of further management, most commonly by endoscopic ultrasound with fine needle aspirate. SCCP is more aggressive than adenocarcinoma of the pancreas with a median survival of three and ten months for those treated with palliative and surgical intent, respectively. The optimal treatment regimen remains unknown, though the uses of radiation therapy, platinum-based regimens, gemcitabine, and 5-FU have all been reported with favorable results. We present a case of primary SCCP in an 81-year-old female who presented with jaundice.
