DE LA ROSA, Carolina et al. Obstructive jaundice syndrome secondary to paracoledocal non-hodgkin b cel lymphoma: a clinical case. Gen [online]. 2014, vol.68, n.3, pp.112-115. ISSN 0016-3503.

Objective: To present the experience of a case of non-Hodgkin lymphoma next to the common bile duct with a ictero-obstructive syndrome. Being a rare presentation. Case report: Male patient, 50 years old, who entered with a compatible clinical of an ictero-obstructive syndrome with two months of evolution, he performed abdominal ultrasound and a contrasted abdominalpelvic tomography with images suggestive of a probable injury in the head of the pancreas and the uncinate process. Because of this we indicate a Endoscopic ultrasound finding injury splenoportal below the isthmus junction and hypoechoic pancreatic of 27x32mm with defined edges, non-related to pancreas or liver; fine needle aspiration puncture guided by endoscopic ultrasound is indicated, which reports, fibrin, hemorrhage and infl ammatory infiltrated by round cells, fibrous nodule, without observing tumor. It is suggested therefore to extract tumor surgical exploration and biliary drainage. It is obtained as intraoperative findings, one injury defined borders, with Histopathological compatible with non-Hodgkin lymphoma of large B cells, next to the common bile duct. Patient receives chemotherapy in cancer center with good evolution. Discussion: Non-Hodgkins Lymphoma B cells, is the most common presentation of lymphoma, his presentation is variable, and is associated with evidence of lymphadenopathy causing obstructive symptoms by extrinsic compression. The diagnosis is based on pathological studies, so making a sufficient specimen and its inclusion in immunohistochemical studies are necessary. Endoscopic ultrasound is considered an important diagnostic tool to hepatobiliary diseases.
