Invasive squamous cell carcinoma arising from an intraductal oncocytic papillary neoplasm demonstrating shared ATP1B1::PRKACA gene fusion
Intraductal oncocytic Electronic Keyboard papillary neoplasms (IOPN) are rare cystic pancreatic neoplasms marked by oncocytic cells and intricate papillary structures.While typically slow-growing, approximately one-third of IOPN cases are associated with invasive adenocarcinoma.In this report, we present an extremely rare case of invasive squamous
