Challenges of Diagnosis: Periampullary Mass-Induced Obstructive Jaundice in a Young Woman.

Periampullary cancers, which include pancreatic adenocarcinoma, ampullary cancer, distal cholangiocarcinoma, and duodenal cancer, present diagnostic and management challenges due to their aggressive nature and nonspecific symptoms. We describe a case of a female patient, age 20, who had obstructive jaundice brought on by a periampullary tumor. Despite difficulties in diagnosis and treatment, including failed endoscopic retrograde cholangiopancreatography (ERCP), the patient underwent a successful pancreaticoduodenectomy (Whipple's resection), and subsequent immunohistochemistry revealed adenocarcinoma with a mixed immunophenotype expressing duodenal and pancreatic markers. This example emphasizes the significance of taking young patients' periampullary tumors into account, the difficulties in diagnosing them, and the possibility of effective surgical surgery throughout this age range.
