Giant pancreatic cystic lymphangioma.

A giant cystic lymphangioma in the pancreatic body-tail was diagnosed as an incidental ultrasound mass in a 41-year-old patient, with a progressive size that had increased in the last year by about 20 cm size. An ultrasound guided fine needle puncture was performed and the result was a benign cystic lesion. Given the increase in size, a surgical intervention was decided. A retroperitoneal cystic tumor dependent on the posterior pancreatic wall was identified and a full laparoscopic resection with pancreas and spleen preservation was performed. The pathological report confirmed the diagnosis of benign cystic lymphangioma. The patient was discharged on the fifth postoperative day without any remarkable complications. After one year of follow-up, the patient remains asymptomatic.
