Primary Pancreatic Lymphoma Diagnosed by Endoscopic Ultrasound

Primary pancreatic lymphoma (PPL) which originates and remains localized to pancreas is very rare (Pancreas 7:1118, 1992). Without histelogic examination, it cannot be differentiated from pancreatic carcinoma; the differentiation is important as treatment and prognosis are different. US, CAT and ERCP findings are not pathognomonic. Rarer still is PPL presenting as acute pancreatitis (AP) (Gastroenteral Clin Biol 23:528, 1999). We present a case of PPL which presented as AP and was diagnosed by EUS |[plus]| FNA.
