Cholestatic syndrome as a presentation of non-Hodgkin lymphoma. A pediatric case report.

Cholestatic jaundice is due to an alteration in conjugated bilirubin secretion; a possible cause is an al- tered bile flow resulting from an obstruction of the extrahepatic bile duct. A lymphoma is the third most common neoplasm in pediatrics, while pancreatic tumors are rare and mostly benign. The clinical mani- festations of retroperitoneal tumors are not very specific and are usually late, so a high level of clinical suspicion is required. The objective of this study is to describe the case of a 7-year-old boy with cholestatic syndrome with a tumor in the head of the pancreas compressing the extrahepatic bile duct. The tumor diagnosis was non-Hodgkin lymphoma (NHL). It is worth noting that the presence of a tumor in this location in pedia- tric age is uncommon.
