Intraductal papillary neoplasm of the bile duct in the middle east: Case report

Intraductal papillary neoplasm of the bile duct (IPNB) is a rare premalignant tumor characterized by papillary growth within the bile ducts, predominantly reported in East Asia. We present a 64-year-old male diagnosed with IPNB with focal stromal invasion, managed successfully with surgical resection. The case highlights unique endoscopic, imaging, and histopathological findings, and provides valuable data describing the unusual presentation of the case and the challenges faced in making the diagnosis. To our knowledge, this is the first reported case from the Middle East, emphasizing the rarity of IPNB in the region. This report underscores the importance of early diagnosis, proper imaging, and clear resection margins for optimal outcomes.
